A serger is a type of sewing machine that is used to finish the edges of fabric. It can also be used to sew decorative stitches, as well as to create ruffles and other types of embellishments. Knits are a type of fabric that are often used for making clothing, as they are stretchy and comfortable to wear. However, sewing knits on a regular sewing machine can be difficult, as they tend to stretch and pucker. A serger can be used to sew knits without these problems.

What is a Serger?

Sergers are incredibly useful machines that can sew a seam, trim the fabric, and finish the edge all in one step. They’re often used for sewing stretchy fabrics or garments that will be worn often, as the finished product is very strong and durable. Sewing with a serger can seem daunting at first, but once you get the hang of it, it’s really not that different from sewing with a regular sewing machine. In this article, we’ll show you how to set up your serger for sewing knits.

Why Sew Knits on a Serger?

If you’ve ever had the misfortune of sewing a knit fabric on a regular sewing machine, you know it can be a frustrating experience. The fabric tends to stretch out of shape, and it’s difficult to get neat, even stitches. A serger solves all of these problems and is specially designed for sewing knits.

How to Sew Knits on a Serger – Step by Step

Sewing with a serger is one of the best ways to finish off raw edges on knit fabrics. If you don’t have a serger, you can use a regular sewing machine, but it won’t be as professional looking or as strong. Here’s a step-by-step guide on how to sew knits on a serger.

1. Start by threading your serger with the correct type and weight of thread. You can find this information in your serger’s manual.

2. Next, set your stitch length and width. For most knit fabrics, you’ll want to use a longer stitch length, around 4 mm. As for width, you can leave it at the default setting or play around with it to see what looks best on your fabric.

3. Once you have your machine threaded and settings dialed in, it’s time to start sewing! Start by sewing a few test stitches on a scrap piece of fabric to make sure everything looks good before moving on to your garment pieces.

4. To sew knits on a serger, simply align the edge of your fabric with the line on your presser foot and lower the needle into the fabric. Then, holding both the top and bottom threads taut, slowly start sewing forward.

5. As you sew, the fabric will be fed through the machine and come out the other end with clean, finished edges. Repeat this process until all of your garment pieces are sewn together.

Tips for Sewing Knits on a Serger

Most modern sewing machines come with an overlock stitch, which is a very close relative of the serger stitch. An overlock machine sews with two or more threads and finishes the raw edge of the fabric as it sews. A serger machine also sews with two or more threads and can also finish the raw edge of fabric, but it does this with a knife that trims the excess fabric as it stitches. For this reason, a serger produces a much neater finish on seams.

Sergers are fabulous machines that can do so much more than just sew knits! When you learn how to use all the features on your serger, you’ll wonder how you ever managed without one.


If you’re having trouble sewing knits on a serger, there are a few things you can try to troubleshoot the problem. First, make sure that your needle is inserted correctly and that the tension is set correctly. If the tension is too loose, the stitches will be too loose and may come undone. If the tension is too tight, the stitches will be too tight and may pucker the fabric.

Next, check the stitch length. The stitch length should be set to 3-4 mm for best results. If the stitch length is too long, the stitches may come undone. If the stitch length is too short, the fabric may pucker.

Finally, make sure that you are using the correct needle and thread for your fabric. For best results, use a ball point needle and polyester thread.

Alternatives to a Serger

If you don’t have a serger, you can still sew knits on a regular sewing machine. You’ll just need to use a zigzag stitch instead of a straight stitch. You may also need to use a wider seam allowance than usual to account for the stretchiness of the fabric.


In conclusion, sewing with a serger is extremely versatile and can be used for a variety of projects. If you need to sew something that is stretchy or has a lot of movement, then a serger is definitely the way to go. With its built-in knife, it can quickly trim away excess fabric as you sew, which makes it ideal for working with knit fabrics.
