If you’re new to sewing with knits on a serger, there are a few key things you need to know in order to get started. This guide will teach you the basics of sewing with knits on a serger, including how to choose the right thread, needle, and stitch settings. With these tips, you’ll be able to sew beautiful, professional-looking stitches on your knit fabrics.

What is a Serger?

A serger is a type of sewing machine that is used to finish the edges of fabric to prevent them from fraying. Sergers are also known as overlock machines. They usually have three or four threads and can create a variety of stitch types.

Why Use a Serger for Sewing Knits?

Sergers are often called overlock machines because one of their main functions is to sew an overlock stitch. An overlock stitch is a type of stitch that sews over the edge of the fabric to finish, or serge, the raw edge so it will not fray.

Most sergers have at least three and sometimes as many as five thread spools. This allows you to create a wide variety of decorative stitches in addition to the overlock stitch. Sergers also typically have a built-in blade that trims away the excess fabric as you sew, giving your garment a professional finish.

If you are sewing with knit fabrics, a serger can be an invaluable tool. Knit fabrics tend to be more difficult to sew than woven fabrics because they can stretch out of shape as you sew them. A serger will help keep your stitches even and prevent the fabric from stretching as you sew.

Another advantage of using a serger to sew knit fabrics is that you can use a narrower seam allowance. With a regular sewing machine, you typically need to use a seam allowance of at least 5/8″ (1.6 cm) so that you can avoid having your stitching show on the right side of the fabric after it has been sewn. With a serger, you can use a much narrower seam allowance because the blade will trim away any excess fabric before it reaches your needle. This means that your finished garment will have less bulk and will lay smoother on your body.

How to Set Up a Serger for Sewing Knits

If you’re looking to sew knits on a serger, you’ll need to take some special considerations into account. Unlike sewing with a regular sewing machine, a serger can sometimes be tricky to set up for stretchy fabrics. But once you know how to do it, it’s easy!

Here are some tips on how to set up a serger for sewing knits:

– Use the right needle. When sewing knits on a serger, you’ll want to use a needle that’s designed for stretchy fabrics. These needles have a slightly smaller diameter than regular needles, and they have a slight taper to the point. This helps them pierce through the fabric without damaging it.

– Use the right stitch. The best stitch to use when sewing knits on a serger is the narrowest zigzag stitch that your machine is capable of making. This will help prevent the fabric from stretching out of shape as you sew.

– Set the correct tension. When sewing with a serger, you always want to err on the side of too much tension rather than too little. This is especially true when sewing with stretchy fabrics like knit fabrics. If the tension is too loose, the stitches will be too big and the fabric will pucker. If the tension is too tight, the stitches will be too small and the fabric will bunch up. The best way to find the perfect tension is to practice on scraps of fabric until you get it just right.

Tips for Sewing Knits on a Serger

Sewing with a serger is different than sewing with a regular sewing machine. A serger can cut and sew the fabric in one step, which means that it can be tricky to get the right tension if you’re not used to it. Here are some tips for sewing knits on a serger:

– Use a lighterweight thread. Sergers can handle heavyweight thread, but it can be difficult to get the tension right.
– Use a smaller needle. A smaller needle will create less friction and make it easier to sew through the fabric.
– Use a stretch stitch. A stretch stitch will allow the fabric to stretch without breaking the thread.
– Use stabilizers. Stabilizers will help keep the fabric from stretching out of shape.
– Sew slowly. Sewing slowly will help you get a better stitch and will prevent the fabric from bunching up.


If you are having difficulty sewing knits on a serger, there are a few troubleshooting tips that may help. First, make sure that your needle is properly threaded and that the presser foot is correctly positioned. Next, check the tension on your serger and adjust it as needed. Finally, experiment with different stitch settings until you find one that works well for the fabric you are working with.


In conclusion, sergers are amazing machines that can make sewing knits a breeze. With the right settings and techniques, you can achieve professional results that will make your friends jealous. So don’t be afraid to experiment and have fun with your serger.
