Top 7 Best Sewing Machines For Knit Fabrics

Knit fabric is stretchy and shrinky, making it hard to sew with a standard sewing machine. If you are on the hunt for the best sewing machine for knit fabric, a serger sewing machine (also called an overlock sewing machine) is the best fit for your needs.

And when choosing a serger, you should take the knit fabric types (weft-knit and warp-knit fabric), stitching types into your very first account.

Besides, available accessories, bobbin-thread lift, and other features (such as differential feed, which helps prevents stretching and puckering on all fabric types) are also worth considering, which will make your machine more versatile and your sewing experience more comfortable.

But with so many serger models in the market, picking the right machine might be a bit tricky and confusing, even for an experienced sewer. All other sergers are either too basic or too advanced.

In this article, I have rounded up 7 best sewing machines for knit fabrics, taking into consideration price and features:

See the overview, pros & cons below.

What Is Kint Fabric?

Fabric can come from various materials, including linen, rayon, spandex, lycra, viscose, and cotton. However, the preparation of almost all fabric falls under two main fabric types: knit or woven.

Woven fabrics have vertical and horizontal threads and are woven on a loom. They are made of warp yarns and weft yarns. On the other hand, knit fabrics are made of interlocking loops of yarns. As a result, they will stretch when you pull them. 

Knit fabric is more flexible than woven fabric, and it is more popular in sewing smaller pieces such as socks and hats. This is because they are super comfortable to wear. However, if you are a beginner or new in the field of sewing, this kind of fabric can be quite frustrating initially.

What Kind of Sewing Machine is Best for Knit and Stretch Fabrics?

#1. Serger or Overlock Machine

The serger machine is considered to be the best machine for stitching knits. Typically, these machines are used for hemming raw edges, but they can also be used to sew knit fabrics because the stitches can stretch easily.

This is quite a popular model of sewing machine that helps you get the desired results. While the drawback of a serger machine is that you cannot do topstitching on it. And it is are less versatile than a sewing machine and not suitable for a beginner.

#2. Coverstitch Machine

This is another kind of machine that is suitable for hemming knits. The stitches are almost similar to the kind of serger machine. However, while one side has thread loops, the other side has two parallel stitches.

These help to stretch the stitches without damaging the fabric. A majority of the popular brand t-shirts are sewed using this machine.

#3. Conventional Sewing Machine

A regular sewing machine is useful when you stitch knits. However, if you do not own a serger, a traditional sewing machine will work too. You can use the stretch stitch for this purpose.

Furthermore, a traditional machine is a great option to sew hem. You can use different kinds of stitches to do a mock coverstitch. If you wish to do topstitching on any knit fabric, the best option is the traditional sewing machine.

How Do I Prepare to Sew Knit Fabrics?

#1. Pre-Shrink the Knit Fabric

Even though the knit fabric label might indicate that the knit fabric is pre-shrunk, it still will shrink unpredictably after washing. So before you start with your sewing work, it is crucial to first pre-wash the material.

Washing the fabric before you start with sewing will shrink the material so it will remain the same size even after you wash it multiple times.

#2. Note the Stretch Amount

It is crucial to note how the knit fabric stretches before you start with your projects. Every knit fabric differs, and you might get different results each time. However, a majority of the patterns suggest the most suitable knits.

Furthermore, fabrics have a stretch gauge that will help you understand how the material will fit once done.

#3. Find the Direction of Stretch

Always make sure to notice in which direction the fabric stretches the most when you cut a knit. In most cases, the direction of the stretch will need to go around the body, not up and down.

You can have a look at the pattern pieces to recognize the direction. Make sure that before you cut, line the pattern pieces parallel to the stretch direction.

How to Choose the Best Serger Sewing Machine for Knit Fabrics?

#1. Which Fabric Are You Going to Use?

The first step to a successful sewing project is to know the type of fabric well. There are many different types of knit fabrics available in the market. Here I will list some of the detailed descriptions that will help you choose better and sew easier.

– Jersey Knit

The Jersey knit fabrics are one of the most familiar fabric types you will come across. This material is the perfect option for comfortable wear. And most of the t-shirts and blouses are crafted with these fabrics.

– Double Knit

This fabric has two layers of fabric, which is why it is called a double knit. The fabric is perfect for beginners to start their sewing journey with because they are easy to handle. Furthermore, the material is sturdy enough; hence you won’t damage it easily.

Last but not least, this fabric accentuates the shape of your body. You can sew dresses, skirts, lightweight jackets, and so much more with this fabric.

– Sweater Knit

The winters are on the way, and so is the season for sweaters. The sweater knits are the best material to stitch nice and cozy sweaters.

Besides, it is also important to have a good sewing machine for such kinds of fabrics. Then you can make your custom-designed sweater and rock the season.

#2. Stitches Type You Make for Your Sewing Projects

To make your sewing project a success, you need stretch stitches. Else, there are chances of them popping or breaking. Here are some basic stitches that will let you easily handle knit fabrics.

– Zigzag Stitch

The first stitch on our list is the zigzag stitch. You might be very familiar with this stitch if you have been stitching for a while. They are the perfect kind of stitches that are suitable on a knit fabric. A zig-zag stitch is 1.4 mm long and 3.5 mm wide.

Since the fabrics are stretchy, do not pull them too much. Pulling will make the fabric look old and damaged.

– Triple Zigzag

If you are looking for a durable stitch, the tripe zig-zag will sort your worries. The triple zigzag offers double the strength of a normal zig-zag.

This kind of stitch is suitable for projects like tents, kites, or outdoor gears. Hence, try the triple zig-zag stitch to add extra strength to your stitches and style to your projects.

– Twin Needle Stitch

A twin needle stitch sews two parallel lines of stitches along with zig-zag interlocked stitches between them. This stitch is not only attractive but is also strong and stretches easily when you pull them apart.

It is recommended that you use a ballpoint twin needle for this purpose because the twin needle avoids any kind of damage to the fabric.

Hints and Tips for Sewing Knit Fabrics

#1. Knit Fabric

The first step to sewing a successful and professional project is to know your fabric well. It is recommended that you start your projects with thick fabrics because they are easier to start sewing with. In addition, sewing on heavy fabric allows you to change your stitches anytime and correct them. Once you familiarize yourself with sewing heavy fabrics, you can start working on knit fabric.

Before you work on any fabric, know its fiber content. While some knit fabrics stretch to a large extent, others may not. Hence, it is important to know the fabric’s stretch extent and pull them to check the same. And every knit fabric is different and they stretch in different patterns, which adds more challenge of your project.

#2. Needle

Knit fabrics have fiber in them, which can be damaged if you use regular needles as they have a sharp head that can damage the look of the fabric.

It is important to note that the knit fabric also has a thicker structure. Hence, the traditional needles may not be the best pick for sewing.

The best needles for sewing knit fabrics are ballpoint twin needles. These needles do not have a pointy head, which makes them a suitable choice for knit fabrics. And they do not damage the fabric and give you excellent finishing and quality stitching.

#3. Thread

Since every fabric is different, they all have different requirements for sewing. Just like knit fabrics require twin needles for better stitching results, the thread also plays an important role in delivering an excellent finish to the project.

But you can not use just any thread for sewing on a knit fabric. The best threads to use on knit fabrics are all-purpose threads. But stretchy threads are also great alternatives.

Final Thoughts
