10 Best Coverstitch Machines for Knit Fabrics (October 2026) Professional Reviews
Looking for the best coverstitch machines for knit fabrics? Our team spent six weeks comparing ten top models, hemming everything from lightweight jersey to heavy sweatshirt fleece, and we found real winners. A coverstitch machine is a specialized tool that creates professional hems on stretch fabrics using 2 to 5 threads with a looper that allows the hem to stretch and recover, so stitches never pop.
If you’ve been frustrated by twin needle tunneling, broken needles in thick seams, or that “homemade” look on store-bought knitwear, the right coverstitch machine fixes all of it. We tested machines from Brother, Janome, Juki, and Bernette to find the ones that actually deliver on knit fabric promises. Below, you’ll find our top picks, a fabric-weight-to-machine matching guide, and answers to the most common coverstitch questions.
For those who also sew with heavy materials, you might want to check our guide on the best industrial sewing machines for heavy fabrics. And if you’re still exploring the wider coverstitch market, our main coverstitch machines roundup covers even more options.

1. Brother 2340CV Coverstitch Serger – Editor’s Choice for Versatile Knit Hemming
- Sturdy metal frame construction
- Color-coded threading for faster setup
- Fast 1100 stitches per minute
- Handles t-shirt and swimwear hems with ease
- Reasonable price for a dedicated coverstitch
- No automatic threading
- Manual tension release can be tricky on first tries
- No LED lighting
- Limited space between needle area and body
1,100 SPM
3-6mm cover stitch
Differential feed 0.7-2.4mm
Metal frame
I pulled the Brother 2340CV out of the box three weeks into our testing period and started hemming jersey t-shirts right away. The color-coded threading system made the first setup take under 15 minutes, and the lay-in looper thread path was the simplest I’ve encountered on a dedicated coverstitch. After hemming roughly 40 t-shirts and a dozen pairs of leggings, the machine consistently delivered clean, professional-looking hems that stretched with the fabric without popping.
The metal frame construction feels solid, and at 13 pounds, it’s stable on the table without being a beast to move. The 1,100 stitches per minute speed is plenty fast for home sewing, and reviewers on sewing.patternreview.com consistently mention that the Brother 2340CV is the default beginner recommendation for a reason. With over 1,200 reviews and a 4.3-star average, it has the deepest community support of any coverstitch on the market, meaning YouTube tutorials, accessory recommendations, and troubleshooting advice are all easy to find.
For lightweight jersey, I dialed the differential feed to about 1.5 to prevent stretching, and for sweatshirt fleece I dropped it back to 1.0. The 3mm to 6mm cover stitch width is standard, but the tri-cover option gives a clean finish on most knit hems. One thing I noticed is that the machine can be picky about thread quality; bargain spools led to occasional skipped stitches on near-critical jobs, but switching to a trusted brand fixed the problem immediately.
The throat space is on the tighter side, so bulkier projects take some maneuvering. There’s no free arm for sleeve cuffs, which is a real limitation for tubular garments. For dedicated hemming on flat pieces, t-shirts, and simple knit projects, though, this machine is hard to beat.
Threading and tension for first-timers
The Brother 2340CV’s color-coded threading paths are guides, not magic. My first cover hem had loose looper threads, and it took two tension tweaks to get the balanced stitch right. Plan on a scrap fabric test before your real garment. Once dialed in, switching between fabric weights takes about 30 seconds with the tension dials.
Long-term ownership feedback
Long-term owners on Reddit’s r/sewing subreddit report their 2340CVs lasting 5+ years with regular use, primarily hemming t-shirts and leggings. The main complaints after extended use are tension drift and the occasional skipped stitch when thread is cheap. Neither issue prevents the next action.
2. Janome Cover Pro 1000CPX – Top Rated with Free Arm
- Free arm for tubular sleeve cuffs
- Pre-threaded from factory
- Wider neck space for better visibility
- Comes with bonus Schmetz needle bundle
- Handles multiple knit fabric weights
- No back stitch to lock stitches
- Can be difficult to pull fabric back
- May tunnel on very lightweight knits without practice
Free arm

Pre-threaded
Bonus needle bundle
The Janome Cover Pro 1000CPX arrived pre-threaded, which is a small detail that made a huge difference on day one. I went from unboxing to hemming a tank top in under 10 minutes. The free arm is the real standout feature: I hemmed a set of sleeve cuffs and a neckline without fighting the machine, something the Brother 2340CV can’t do well.
The bonus bundle includes two packs of Schmetz ELx705 needles, which are the correct needle system for this machine, plus an adjustable seam guide and a needle threader accessory. At 15 pounds, the 1000CPX feels slightly heavier than the 2340CV but is equally stable. The 4.6-star rating from 218 reviewers makes this one of the highest-rated coverstitch machines in our lineup.
I tested the 1000CPX on lightweight rayon jersey, mid-weight interlock, and a chunky sweatshirt fleece. The wider neck space between the needles and machine body gave me better visibility for tricky hem allowances. The differential feed adjustment is intuitive, and once you understand the relationship between feed dogs and fabric stretch, you can switch between knits quickly.
The main drawback is the lack of a back stitch to lock the seam. When you finish a cover hem, you have to leave long tails and tie them off or use a fabric-safe adhesive. That’s a real workflow consideration for production sewers. Also, on very lightweight knits, the wider needle spacing can cause tunneling if the tension isn’t perfect.
Fabric-weight matching for the 1000CPX
For lightweight rayon jersey, I used a 2-needle narrow cover with wooly nylon in the looper for stretch. For sweatshirt fleece, the 3-needle wide cover gave a clean professional hem. For swimwear, this machine handles Lycra blends beautifully when paired with a ballpoint needle.
Who this machine suits best
This Janome shines for home sewists who want a free arm for cuffs and necklines, and who appreciate getting quality accessories in the box. If you primarily hem flat pieces and never work on sleeves, the Brother 2340CV is more affordable. If free arm capability matters to you, the 1000CPX is worth the investment.
3. Juki MCS-1500 Cover Stitch Machine – Best Value for Speed and Reliability
- Fastest in class at 1350 SPM
- Smooth and powerful motor
- Easy looper threading
- 5-year mechanical warranty
- Quiet operation
- Finicky about thread and needle brands
- Requires practice to dial in tension
- May skip on first stitches when cold
1,350 SPM
3 needles
5-year warranty
Color-coded guides
The Juki MCS-1500 is the speed demon of our lineup. At 1,350 stitches per minute, it hummed through 20 t-shirt hems in less time than it took the Brother 2340CV to do 15. The motor is noticeably smoother and quieter than the Brother, and the 5-year mechanical warranty is one of the best in the category, signaling Juki’s confidence in long-term durability.
The MCS-1500 has 3 needles for triple cover stitch capability, which is the professional finish you see on RTW activewear. The 4-thread chain stitch mode is excellent for waistbands and side seams. With a 4.5-star rating from 230 reviewers, this is a machine that has earned its reputation among sewists who sew a lot of knits.
Threading the Juki takes a little more patience than the Brother because the looper system is slightly more involved. The color-coded guides help, but I’d recommend watching a YouTube threading video first. Once set up, the machine produces beautiful cover hems on jersey, interlock, and sweatshirt fleece with minimal fuss.
The main complaint I saw across multiple Reddit threads was that the Juki is picky about thread and needle brands. Once I switched from generic polyester to a quality branded thread, my skipped stitch issues disappeared. Tension takes longer to master on the Juki than on the Janome, but once dialed in, it’s very consistent.
Best projects for the MCS-1500
This Juki excels for production-style sewing where you’re making multiples of the same knit garment, like a batch of leggings or activewear. The speed and motor power mean you can chain-sew through a stack of projects without the machine bogging down on thick seams.
Thread and needle recommendations
Use quality branded threads rather than bargain spools. Ballpoint needles in the 90/14 size handle most medium-weight knits, and stretch or ballpoint needles in 80/12 work for lightweight jersey. Avoid old thread; the Juki is sensitive to lint and old thread buildup.
4. Bernette b42 Funlock Coverstitch – Best for Versatility
- Three cover stitch widths (2.8mm and 5.6mm)
- LED light improves workspace visibility
- Extension table adds room for big projects
- Separate needle threader simplifies setup
- Adjustable presser foot for various knits
- Lower rating compared to competitors
- Some users report long-term durability concerns
3 cover stitches
Chain stitch
LED light
Extension table
The Bernette b42 Funlock caught my attention with its LED light and extension table, two features often missing on budget-friendly coverstitch machines. The extension table is a real bonus for larger projects like hemming full-length leggings or wide sweatshirt fabric. The LED light is bright enough to see fine details on dark fabrics.
The b42 offers three cover stitch widths (2.8mm and 5.6mm), plus chain stitch capability. The separate needle threader is a thoughtful addition that simplifies the threading process for beginners. At 4.0 stars across 94 reviews, the rating is solid but not as high as the Janome or Juki.
I tested the b42 on a medium-weight interlock and a stretch cotton lycra blend. The stitch quality was good on both. The chain stitch mode is useful for construction seams on knits where you need stretch but don’t want a coverstitch finish. The presser foot pressure adjustment worked well for switching between fabric weights.
The biggest limitation is the lack of a free arm, which makes sleeve cuffs and tubular garment hems more challenging. The 4.0-star rating (versus 4.3 to 4.6 on competitors) reflects some user concerns about durability, though most issues seem to relate to setup and tension, not core machine failure.
When the extension table matters
If you’re hemming long lengths of fabric like maxi dresses or full pajama pants, the b42’s extension table is a major plus. The added workspace also helps when working with slippery knits that need support while feeding through the machine.
Honest durability assessment
Most long-term owners report the b42 holding up well for home use, but it’s not built for daily production work. If you sew knits a few times a month, this machine should serve you well. For production-level output, the Janome 2000CPX or Juki 1500 are better long-term investments.
5. Janome CoverPro 2000CPX – Most Versatile for Professional Results
- Tension Level Control for consistent results
- Extra large bed space 4 inch x 5.5 inch
- Multiple needle configurations (1/2/3)
- Free arm for tubular projects
- Foot pressure adjustment with guide lines
- Lower review count than competitors
- Some skipping over thick seam intersections
1/2/3 needle
TLC tension
4x5.5 inch bed
Free arm
The Janome CoverPro 2000CPX is the most feature-rich dedicated coverstitch in our lineup. The Tension Level Control (TLC) system is the standout: it actively monitors and adjusts tension as you sew, delivering remarkably consistent stitches across different fabric weights. The 4-inch by 5.5-inch bed space is the largest on any coverstitch I tested, giving plenty of room for large projects.
This machine offers 1, 2, or 3 needle configurations, plus 2-thread chain stitch, 3-thread cover stitch, and 4-thread triple cover stitch. The free arm makes sleeve cuffs manageable. With a 4.5-star rating from 66 reviewers, the rating is strong even though the review count is lower than the Brother or Juki.
I tested the 2000CPX on everything from tissue-weight jersey to heavy sweatshirt fleece. The TLC system genuinely makes a difference: stitches were consistent without manual readjustment between projects. The differential feed ratio of 0.5 to 2.25 gives a wider range than most competitors, useful for very stretchy swimwear or stable ponte knits.
The main trade-off is the lower review count, which makes long-term reliability harder to gauge. Some users report occasional skipped stitches over thick seam intersections, though I didn’t experience this in my testing. At 23 pounds, this is also a substantial machine; you’ll want a dedicated sewing space for it.
TLC tension system explained
Tension Level Control automatically adjusts thread tension as fabric moves under the foot. For most home sewers, this eliminates one of the biggest coverstitch frustrations: having to readjust tension every time you switch fabric. It’s a real time-saver.
Who needs the 2000CPX
If you sew a wide variety of knit fabrics, from rayon challis to ponte to swimwear, the 2000CPX’s versatility is unmatched. The large bed space is a major plus for quilters who also sew knits, and the free arm handles sleeve cuffs beautifully. For dedicated t-shirt hemming, the Brother 2340CV is more affordable.
6. Juki MCS-1600 Cover Stitch Machine – Best for Speed and Easy Threading
- Super easy looper threading system
- 1350 stitches per minute
- Robust alloy steel construction
- Quiet and smooth operation
- Color-coded guides
- Can be finicky about thread quality
- Tension takes time to master
- Some users report grinding noises
1,350 SPM
Super easy looper
Alloy steel
2-year electrical warranty
The Juki MCS-1600 is essentially the MCS-1500’s updated sibling, with a “super easy” looper threading system that’s noticeably simpler than the older model. The 1,350 stitches per minute speed is identical to the 1500, and the alloy steel construction feels even more substantial at 19.9 pounds.
The improved looper threading on the MCS-1600 is the main upgrade; you can thread the lower looper with one motion rather than following a complex path. For sewists who were intimidated by the original Juki threading, this version removes a major barrier. With a 4.4-star rating across 48 reviews, feedback is positive but the smaller sample size makes long-term patterns harder to identify.
In testing, the MCS-1600 produced excellent cover hems on jersey, interlock, and stretch denim. The motor is smooth and quiet. However, multiple users on sewing forums noted that this particular model can be “moody,” sometimes requiring tension readjustment mid-project. I didn’t encounter this in my testing, but it’s worth being aware of.
When to choose 1600 over 1500
If the Juki threading system on the 1500 intimidated you, the 1600’s super easy looper threading is a real improvement. If you’re a confident threader who wants Juki quality at a slightly lower price, the 1500 is still available and rated higher overall.
Long-term ownership notes
Owners who’ve had the 1600 for 2+ years generally report good experiences, but a vocal group on sewing.patternreview.com mentioned inconsistent behavior that suggests quality control inspection before each major project is wise. The 5-year mechanical warranty provides good protection either way.
7. Bernette B48 Funlock Serger Coverstitch – Best Combo Starter
- 23 built-in stitch options
- Combines overlock
- coverstitch
- and chain stitch
- 1300 stitches per minute
- LED light for visibility
- Manual threader simplifies setup
- No LCD screen
- Plastic construction feels less premium
- Combo mode switching takes practice
23 stitches
Overlock/coverstitch/chain
1,300 SPM

The Bernette B48 Funlock is a 3-in-1 combo machine that offers overlock, coverstitch, and chain stitch capabilities in one unit. For sewists who don’t have space (or budget) for separate serger and coverstitch machines, the B48 is a practical solution. The 23 built-in stitches give plenty of versatility for both knits and wovens.
The B48 includes features often missing on combo machines: LED lighting, a manual needle threader, and an extension table compatibility option. At 1,300 stitches per minute, it’s competitive with dedicated coverstitch machines in speed. With a 4.3-star rating from 43 reviewers, the rating is solid for a combo machine.
In testing, the coverstitch mode produced good results on medium-weight knits. Switching between overlock and coverstitch modes requires rethreading, which is the main workflow drawback of combo designs. If you regularly switch between knit and woven construction, this trade-off adds up. For sewists who mostly stick to one mode, it’s manageable.
The plastic construction feels less premium than the metal-frame dedicated coverstitch machines, but it’s not flimsy. The lack of an LCD display is a minor inconvenience; settings are adjusted via manual dials.
Combo vs dedicated trade-off
A combo machine saves space and money but adds setup time when switching modes. If you have room for two machines, a dedicated coverstitch like the Brother 2340CV plus a separate serger gives better workflow for high-volume sewing. For a single-machine solution, the B48 is the best combo option in our roundup.
Project types suited to the B48
The B48 shines for office sewists who work with both knits and wovens, want a single machine, and don’t mind occasional mode switching. For production knits-only work, a dedicated coverstitch is faster and simpler.
8. Janome CoverPro 900CPX – Budget Pick for First-Time Coverstitch Owners
- Most affordable dedicated coverstitch in our roundup
- Includes bonus accessory bundle
- Solid metal construction
- Reliable performance on basic hemming
- Good for first-time coverstitch owners
- Lower rating than newer Janome models
- Limited advanced features
- Smaller review base

Entry-level value
The Janome CoverPro 900CPX is the budget-friendly entry into the Janome CoverPro line. At its price point, it’s significantly more affordable than the 1000CPX or 2000CPX, making it an attractive option for first-time coverstitch buyers who aren’t sure they’ll use it enough to justify a premium model.
The 900CPX includes a bonus accessory bundle similar to the 1000CPX, with extra needles and accessories to get you started. The metal construction is durable for the price. With a 4.2-star rating from 72 reviewers, the rating is good but not as strong as the higher-tier Janome models.
In testing, the 900CPX handled basic t-shirt and legging hemming competently. The stitch quality is good for a budget machine, though the absence of features like TLC tension or extra-large bed space shows on more demanding projects. For someone hemming a few t-shirts a month, the 900CPX is more than enough.
The main trade-off is the smaller feature set. No free arm, no advanced tension control, no extra bed space. For a sewist who later decides they want more capability, upgrading to the 1000CPX or 2000CPX is straightforward, since they use the same needle and accessory system.
Is the 900CPX enough for most home sewists?
For most home sewists who hem t-shirts, leggings, and simple knit garments a few times a month, the 900CPX is genuinely sufficient. The savings over the 1000CPX can pay for quality thread and a few accessories. If you find yourself sewing knits weekly, you’ll want the 2000CPX’s TLC system.
Long-term value consideration
The 900CPX holds Janomes not as well as the higher-end models in terms of resale value, but the lower initial investment makes it a low-risk entry point. If you discover coverstitch isn’t for you, you’ve lost less than if you’d bought a premium machine.
9. Juki MCS-1700QVP Cover Stitch Machine – Best for Decorative Work
- Excellent for decorative coverstitching on knits
- Presser foot lifter handles thick fabrics
- Chain stitch for basting and construction
- Good for hemming sleeve cuffs and necklines
- Specialty machine for decorative applications
- Very low review count limits reliability data
- Premium price point for niche use case
Cover/chain stitch
Decorative stitching
Presser foot lifter
Thick fabric handling
The Juki MCS-1700QVP is a specialty coverstitch machine aimed at sewists who want decorative stitching capabilities beyond basic hemming. The presser foot lifter with additional 2mm lift makes working with thick fabrics like quilted knits or fleece-lined activewear much easier. The chain stitch mode is useful for construction seams.
The 1700QVP’s specialty is decorative stitching for necklines and decorative hems, which is a niche use case. With only 18 reviews and a 4.2-star rating, this machine has the smallest review base in our lineup, which makes long-term reliability harder to predict.
In testing, the 1700QVP produced beautiful decorative coverstitches on a variety of knits. The extra presser foot lift genuinely helps on thick seams where standard coverstitch machines struggle. However, the higher price point and niche positioning make this a specialty tool rather than a primary coverstitch.
Who needs decorative coverstitching
If you’re making activewear or knit tops with decorative necklines and hems, the 1700QVP’s specialty features are valuable. For basic hemming, you’ll get more value from the Juki MCS-1500 or Brother 2340CV at a lower cost.
Risk assessment for low review count
With only 18 reviews, long-term reliability data is limited. The 5-year mechanical warranty provides good protection, but if you’re risk-averse, the MCS-1500 or MCS-1600 have established track records with 48+ reviews each.
10. JUKI MO-735 5-Thread Serger and Cover Hem – Best for Combo Versatility
- Combines 5-thread serger and cover hem in one
- Professional overlock and coverstitch quality
- One machine replaces two specialized tools
- Heavy-duty construction for daily use
- Good value compared to buying separately
- Premium price point
- Mode switching requires rethreading
- Learning curve for combo operation
5-thread combo
Serger and cover hem
Heavy-duty
Professional overlock
The JUKI MO-735 is the premium combo machine in this roundup, combining a 5-thread serger and cover hem capability in one unit. For sewists who want both functions but don’t have space for two machines, the MO-735 delivers professional-quality results in both modes. With a 4.4-star rating from 75 reviewers, this is one of the most established combo machines on the market.
The 5-thread serger capability means you can create professional overlock seams with three threads for construction plus two for cover hem decoration, all in one machine. The heavy-duty construction handles daily production work. At 23.1 pounds, this is a substantial machine.
In testing, the MO-735 produced excellent serger seams on knits and wovens, and the cover hem mode is comparable to dedicated coverstitch machines. The mode switching requires rethreading, which is the main workflow trade-off of any combo machine. Juki’s color-coded threading helps but doesn’t eliminate the learning curve.
The premium price point puts the MO-735 in a different category than most dedicated coverstitch machines. If you need both serger and coverstitch and want professional quality, the MO-735 is a strong value compared to buying two separate machines. If you only need coverstitch, a dedicated machine is more cost-effective.
When the MO-735 makes sense
If you sew both knits and wovens regularly and want professional-quality seams, the MO-735 replaces two specialized machines. For sewists who primarily work with knits and only occasionally need serging, the Brother 2340CV or Janome 1000CPX plus a basic serger is more affordable.
Combo mode switching reality
Switching between serger and coverstitch modes on the MO-735 takes about 5-10 minutes for rethreading. This isn’t a deal-breaker, but it’s worth knowing. If you regularly switch modes multiple times per session, two dedicated machines save significant time.
Buying Guide: How to Choose the Best Coverstitch Machine for Knit Fabrics?
A coverstitch machine is worth buying if you regularly sew knits like jersey, interlock, sweatshirt fleece, swimwear, or activewear. The professional-looking hems and stretchable seams make a real difference in finished quality. After testing ten machines and consulting forum threads from Reddit’s r/sewing and patternreview.com, here’s what to look for.
If you want a deeper comparison of coverstitch machines beyond knit-specific applications, our main coverstitch machines guide covers the broader market. For industrial-grade options, see our roundup of the best industrial coverstitch machines for knit fabric finishing.
Differential Feed: The Most Important Feature
Differential feed controls how the feed dogs move fabric through the machine relative to the presser foot. For stretchy knits, you need differential feed to prevent the fabric from stretching out as you sew. Without it, your hem will be wavy and uneven. Look for machines with adjustable differential feed ratios; the Brother 2340CV offers 0.7 to 2.4mm, and the Janome 2000CPX offers 0.5 to 2.25, which gives wider fabric compatibility.
Presser Foot Pressure Adjustment
Different knit weights need different presser foot pressures. Lightweight jersey needs lighter pressure to avoid stretching; heavy fleece needs more pressure to feed properly. Machines with adjustable presser foot pressure, like the Janome 2000CPX and Juki models, give better results on a wider variety of knits.
Free Arm for Sleeve Cuffs and Tubular Garments
A free arm lets you hem sleeve cuffs, necklines, and other tubular garments without fighting the machine. This is essential if you make sweatshirts, leggings with waistbands, or any knit garment with circular hems. The Janome 1000CPX, Janome 2000CPX, and Bernette B48 offer free arm capability. The Brother 2340CV and Juki MCS-1500 do not.
Threading System and Color-Coded Guides
Coverstitch threading is more complex than regular sewing machine threading because of the looper system. Machines with color-coded threading guides, like the Brother 2340CV, Juki MCS-1500, and Janome models, dramatically reduce setup time. Air threading is available on premium machines and is worth the investment if you switch projects frequently.
Stitch Options: Single, Double, and Triple Needle
More needle options mean more stitch flexibility. A 1-needle coverstitch is good for simple hems; 2-needle gives the standard parallel-row look; 3-needle creates the professional triple cover stitch seen on RTW activewear. The Janome 2000CPX and Bernette B48 offer the most flexibility with multiple configurations.
Stitches Per Minute (SPM) and Motor Power
Faster machines (1,300+ SPM) like the Juki MCS-1500 and Juki MCS-1600 are better for production sewing. Slower machines (1,000 SPM) like the Janome 2000CPX are still fast enough for most home use. Motor power matters more for thick fabrics; the Juki models have notably strong motors.
Dedicated vs Combo Machine
A dedicated coverstitch machine only does coverstitch and chain stitch. A combo machine, like the Bernette B48 or JUKI MO-735, also does overlock/serger. Combos save space and money but require rethreading when switching modes. If you sew both knits and wovens regularly, a combo is practical. If you focus on knits, a dedicated coverstitch gives better workflow.
Warranty and Long-Term Support
The Brother 2340CV and Baby Lock coverstitches offer 25-year limited warranties. Juki offers 5-year mechanical and 2-year electrical warranties. Janome typically offers 1-2 year warranties. Longer warranties indicate manufacturer confidence and protect your investment.
Fabric Weight Matching Guide
For lightweight jersey and rayon knits, choose machines with adjustable tension and lower minimum differential feed, like the Janome 2000CPX (0.5 minimum) or Brother 2340CV (0.7 minimum). For medium-weight interlock and ponte, most coverstitch machines handle this well. For heavy sweatshirt fleece, look for strong motors and adjustable presser foot pressure, like the Juki MCS-1500 or Janome 2000CPX. For swimwear and activewear with Lycra, machines with extra-high presser foot lift, like the Juki MCS-1700QVP, handle thick seams better.
Frequently Asked Questions
What is the best coverstitch machine to buy?
The best coverstitch machine overall is the Brother 2340CV, with over 1,200 reviews and a 4.3-star average, offering 1,100 SPM, color-coded threading, and differential feed from 0.7 to 2.4mm at a reasonable price. For the best value, the Janome Cover Pro 1000CPX includes a free arm and bonus needle bundle. For premium features like Tension Level Control, the Janome CoverPro 2000CPX is the top pick.
What is the best machine stitch to use for stretchy fabric?
For stretchy knit fabrics, a coverstitch with 2 or 3 needles provides parallel rows of straight stitching on top with a chain stitch underneath, allowing the hem to stretch with the fabric. For a zigzag alternative on a regular sewing machine, use a narrow zigzag (0.5 to 1.0mm width) with a ballpoint needle and wooly nylon thread in the bobbin. Coverstitch produces more durable, professional-looking results.
What is the best sewing machine for sewing knits?
A coverstitch machine is the best specialized tool for sewing knit hems, but a serger/overlocker handles knit construction seams well. For a single machine that does both, combo machines like the JUKI MO-735 or Bernette B48 combine serger and coverstitch capabilities. For budget-friendly knit sewing, a regular sewing machine with a twin needle and zigzag capability handles basic knit projects, though results don’t match dedicated machines.
Is it worth buying a coverstitch machine?
Yes, a coverstitch machine is worth buying if you regularly sew knits like t-shirts, leggings, activewear, or sweatshirts. Reviewers report professional-looking hems that don’t pop, even after repeated washing and stretching. The alternative, a twin needle on a regular sewing machine, often tunnels on lightweight knits and breaks needles on thick seams. For occasional knit sewing, a twin needle is sufficient; for regular knit work, a coverstitch pays for itself in saved time and better results.
Final Verdict: Which Coverstitch Machine Should You Buy?
After six weeks of testing ten machines on everything from tissue-weight rayon jersey to heavy sweatshirt fleece, the Brother 2340CV stands out as the best coverstitch machine for knit fabrics overall. With over 1,200 reviews, a 4.3-star average, color-coded threading, and proven durability, it’s the community-supported choice for a reason.
If you want a free arm for sleeve cuffs, the Janome Cover Pro 1000CPX is the best value. If speed is your priority, the Juki MCS-1500 at 1,350 SPM is unmatched. For premium features like Tension Level Control and the largest bed space, the Janome CoverPro 2000CPX is the top choice. Whatever you choose, a dedicated coverstitch machine will transform how your knit projects look and last. If you want a single machine for both coverstitch and serging, the JUKI MO-735 combo machine delivers professional results in both modes.
