You’ll get professional-looking hems on knits with the Brother CV’s three coverstitch options. But the plastic presser foot and steep price tag may make you reconsider. With its specialized coverstitch functions, the 2,340CV makes quick work of finishing edges on stretchy fabrics.

Sail through necklines and hems on knit tops and athletic apparel with the built-in 2, 3 or 4 cover stitch options up to 6mm wide. The convenient lay-in threading system and 1100 stitches per minute capability help you achieve great results fast.

However, some users report issues with lightweight knits. And the lack of an all-metal build keeps this model from being a long-lasting workhorse. Although it delivers quality results for some sewers, assess your budget and project needs before investing $500 in this single-purpose serger.

Janome CoverPro 900CPX Coverstitch Machine

Janome CoverPro 900CPX Coverstitch Machine
The Janome CoverPro 900CPX is a heavy duty coverstitch machine made for someone wanting professional hems without all the fuss. As an expert sewer, I know this Janome can produce beautiful coverstitching for hemming knit garments.

But mastering the tension adjustment and learning the operation takes time, even for a pro. Unlike industrial machines, the stitch quality is close but not identical. With practice you’ll get great results hemming dresses, pants, and other stretchy fabrics.

The lack of speed control poses a challenge. Yet this sturdy, quality coverstitch machine from a reputable brand delivers neat hems and withstands frequent use. Janome’s coverstitcher requires an investment of time, but liberates you from wavy seams with the perfect professional finish.

Overall Pros and Cons

Overall Pros and Cons
You’re shopping around for a serger with coverstitch capabilities. An all-in-one serger and coverstitch machine offers efficiency but has a few tradeoffs. Combining serging and coverstitch functions saves time switching between separate machines.

However, some models compromise on performance compared to dedicated serger and coverstitch options. Compact designs can also limit workspace, tension control, stitch quality, and fabric handling. Still, a good combo machine produces high-quality seams and hems if the limitations don’t pose issues for your projects.


  • Hem knits professionally in one step.
  • Create strong seams and prevent fraying.
  • Convert between stitches easily.

Sergers with built-in coverstitch give home sewers professional results when hemming knit garments. The ability to serge seams and finish edges prevents fraying for a polished look. Built-in stitch conversion eliminates the need to change machines, saving time and frustration.


You’ll want to clean the machine after sewing through heavy fabric or lint picks up in hard to reach areas. The combo serger coverstitch machines require frequent threading changes between the two functions.

While they save space and cost over two dedicated machines, you’ll spend time swapping parts and rethreading to switch stitches. Test fabric compatibility before projects, as lightweight knits can snag on the cutters.

Auto tension helps simplify adjustments but the stitch quality may disappoint sewists used to standalone sergers.

Despite fast edge finishing, noisy operation and frustration rethreading dampens excitement for the versatility of this budget-friendly, space-saving, multi-stitch combo machine.

Does It Sew Different Fabrics Well?

Does It Sew Different Fabrics Well
When considering how well a serger with coverstitch sews different fabrics, it’s important to examine key types like swimsuit lycra, lightweight drapey jersey, medium weight stable cotton jersey, heavyweight knit, and stretch denim.

You’ll want to test sew samples to see which models and settings handle your projects best.

Swimwear Lycra

Don’t worry, these sergers are designed and equipped to handle swimwear lycra and other stretchy fabrics with ease, gliding seams as sleek as a dolphin. The serger/coverstitch combination machines have you covered head to toe in stylish lycra suits to hit the beach in.

With professional finishing capabilities for knitwear’s tricky tendencies, the serger provides your swimwear with stretchy seams and hems that last lap after lap in the pool without unraveling. You’ll be styling and profiling your handmade lycra creations with the perfect overlock stitch.

Lightweight Drapey Jersey

You can finesse those delicate jersey knits without worrying about skipped stitches or wavy seams. Select the right needle type and thread weight for knits. Try a narrow coverstitch width and light presser foot pressure.

Use the serger setting for seams and avoid pulling on the fabric. Let the machine do the work – don’t tug or stretch the knit. For hems, a twin needle coverstitch provides a flat seam, allowing the jersey to drape smoothly.

With some practice adjusting tension, the coverstitch creates a professional finish.

Medium Weight Stable Cotton Jersey

It’ll cope with medium weight cotton jersey, but watch the differential feed to prevent wavy seams. To master a serger with coverstitch takes time – learn threading, tension, and stitch options fully. Practice on scraps first. Stitch quality improves as you gain experience. Though noisy, it handles stable cotton well for garments.

Adjust the differential feed and test the stitch on scraps to prevent wavy seams on medium weight cotton jersey.

Heavyweight Knit

You’d power through heavy sweats and thick fleece knits, creating strong seams that move with the hefty fabric. The differential feed prevents tunneling on heavyweight knits. Higher speeds add noise but quickly finish heavyweight projects.

Consider machines like the Bernette b48, Juki MO-2000QVP, and Janome CoverPro 900CPX for heavyweight knit sewing. Their powerful motors and sturdy construction can handle thick layers and challenging fabrics.

Stretch Denim

It sounds like with some adjustments, you can sew stretch denim smoothly on this machine. Adjusting the differential feed and using the right needles, you’ll get professional finishes on stretch denim.

The coverstitch capability handles hems and prevents wavy seams. Compatible with a variety of fabrics, it’s a versatile machine. While noisy at high speeds, lower speeds reduce sound for sewing stretch denim or delicate materials.

With serger techniques and coverstitch benefits, you’ll achieve great results on denim with stretch.
