What is the Best Coverstitch Sewing Machine?

Coverstitch sewing machines are used to create a professional-looking hem to garments and evenly apply trims to flat seams. They are especially handy for people who like to make clothes from knit fabrics and need to make seams that retain some stretch. The coverstitch sewing machine works with either one, two or three needles on top and a thread looper below that weaves thread through the stitches to form a double-locking chain.

Quick Recommendation

Great for hobbyists, home professionals and everything in between, the Juki MO-735 is our top pick for a coverstitch sewing machine. 

Sewing is done from the top of the material with the fabric edge underneath and it creates a single straight stitch for every needle that is used on the top and a chain stitch over the raw edge below. I chose Coverstitch machines from Brother and Janome and a hybrid coverstitch/serger machine from Juki for this review to provide a variety of options in feature and cost.

How to Choose the Coverstitch Machine That Is Right for You

The first thing to consider when comparing these three models is the features that they all have in common. Each machine has differential feed which allows you to change the setting for how much material is fed through the machine. Adjusting the knob for this setting will help you prevent “tunneling” that can occur between stitches or put light gathering into garments where it is wanted. Both the Brother and Janome machines can be used with one, two or three needles while the Juki takes stitching to a whole new level! The combination of serger and coverstitch features make it the most versatile machine available.

Juki MO-735

Many people disagree about the advantage of combining the functions of a serger with those of a coverstitch sewing machine. Many find them more difficult to thread and to switch from one function to the other. The Juki MO-735 is no exception but once the technique is mastered, the process becomes much faster and easier.

Another complaint many buyers share about the Juki MO-735 is that the instruction manual is difficult to impossible to understand. Fortunately, the instructions on YouTube make it much easier to thread the machine and use the different stitches.

The Problem with Overlock/Serger Machines

When overlock machines, or sergers, were first introduced on the market, one of the biggest problems many people had with them was threading. A single mistake in threading any of the three or four spools of thread could result in poor stitch quality. Not only was it difficult to find the problem in the threading guide, there was always the potential for the poor stitching to be from inaccurate tension settings. I know this firsthand because I took my first serger out to the trash dumpster and happily threw it in after two repairs and numerous attempts to thread it without any success.

Janome CoverPro 1000CPX

Although a coverstitch sewing machine is threaded in much the same way as a serger, there have been many improvements since the original models. They also differ in that the coverstitch machine creates a coverstitch on the bottom of the fabric and it doesn’t cut the material off as the seam is sewn. The Juki MO-735 is the only machine in this review that allows you to choose between the overlock and coverstitch functions.

Both the Brother and Janome machines use three needles and three spools of thread. All three machines are color-coded to simplify the threading process and, like the Juki, videos are available on YouTube to help you thread and use the Brother and Janome machines.

Brother 2340CV

All three of these coverstitch sewing machines are from leading brands of regular sewing machines so that you may already have a favorite. Going by brand alone may be all you need to make the right choice as long as you will be using the coverstitch machine for the same level of work that you use your regular sewing machine.


If you want a machine that will make it easier to hem the knit garments you make for yourself, the Brother 2340CV will probably meet your needs. If you are going to take on the job of making leggings for your daughter’s gymnastics team, you may want to move up to the Janome CoverPro. For use in a home business of making custom leggings, the Juki MO-735 is the closest thing to a commercial Coverstitch sewing machine that you can buy for the home.

Most sewers find that a coverstitch machine makes a valuable addition to their sewing room. For those who make knit garments or who need a tool that will help them create a smoother curved hem, no other type of sewing machine will meet the demand better. It is the frequency of use and the need for the most professional results that should guide you in making your choice. Once you have determined your need for durability and quality performance, look at the differences in features that will impact your sewing needs. Sometimes the smallest detail can make a big difference in the quality of your results.

Coverstitching Machine

The Basics of Coverstitching

A coverstitch machine is a specialty sewing machine that is primarily used to create hems. Although coverstitching works well on woven fabrics by keeping them from raveling, they are especially useful for hemming knit fabrics. The stitch it makes maintains the stretch in the fabric and doesn’t pucker as is the case when you sew stretchy fabrics with a traditional sewing machine. To see what a coverstitch looks like, you can look at the hem of almost any t-shirt.

The coverstitch machine uses one, two, or more spools of thread on top and one bobbin on the bottom that is fed through a looper. The latter feature is what causes the thread to form a chain stitch across the raw edge of the fabric. Some sewers like to use different colors of thread on the top spools to add a decorative touch to some of their sewing.

Overlock vs Coverstitch

These two types of machines are very similar in the way they work with one significant difference: The overlock machine has a blade built-in that trims the seams and stitches over them as you sew. This feature makes it easy to sew knit garments without having to go back over them and finish the seams to prevent stretching or raveling.

The coverstitch machine, on the other hand, has no blade and is used primarily for hemming. Many sewers find that the most difficult part of sewing many types of garments is in getting an even, professional quality hem. If you plan on sewing a lot of knits, you may want to invest in both types of specialty machines.

Tips for Creating the Perfect Coverstitch Hem

  • If you have an overlock machine, serge the edge of the hem before coverstitching. You should be able to feel the stitching through the fabric to help you keep the hem straight while you sew.
  • When working with woven fabrics, mark the hem and press upwards before stitching to get an evenly stitched hem.
  • If you are shopping for a new coverstitching machine, make sure it has the free arm feature. This is essential for handling smaller items like pant legs or children’s clothing items.
  • Check out the tutorial for your coverstitch machine on YouTube. Many brands offer demonstrations on threading, stitching, and using various stitching techniques. It’s also a good way to get troubleshooting tips in case you aren’t getting the results that you expected.
