If you are on the hunt for the best sewing machine for knit fabric, there are few key features that you should be looking out for. The best sewing machine for knit fabric is a serger machine. So when choosing a serger, you should take the knit fabric type, stitching type into your very first account. Besides, available accessories, bobbin-thread lift, and other features can also make your machine more versatile.

But picking the right machine might be a bit tricky and confusing with so many models in the market, even for an experienced sewer.

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?

When you work with fabrics, there are generally two types of materials that you come across. First is woven, and the next is a knit fabric. Woven fabrics have vertical and horizontal threads and are woven on a loom. They are also known as the warp and weft.

On the other hand, knit fabrics are made of interlocking loops. They are knitted fabrics that will stretch when you pull them. While some stretch up-down, others stretch side to side as well. This gives you a four-way stretch.

One reason why knit fabrics are so popular is that they easily stretch and are super comfortable to wear, and it is one of the easiest materials that you can sew. However, if you are a beginner or new in the field of sewing machines, the material 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 for stitching knits. If you work a lot with the knit fabric, it is highly recommended that you invest in one of these machines.

This is quite a popular model of sewing machine that helps you get the desired results. The serger stitches can be stretched easily. Hence, when you stretch the fabric, the stitch glides with the material.

While the only disadvantage of the serger machine is that you cannot do topstitching.

#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.

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 the purpose.

Furthermore, a traditional machine is a great option to sew hem. You can use different kinds of stitches to do a mock cover stitch.

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

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. Thus, it will remain the same size even after you wash it multiple times.

Even though the knit fabric label might mention otherwise, the fabric can still shrink after washing. Hence, the safest way out of this is to wash the knit fabric before stitching.

#2. Note the Stretch Amount

It is crucial to note how the knit fabric stretches before you start with your projects. Every fabric differs, and you might get different results each time. 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 while you cut a knit. Often, the direction of the stretch will go around the body.

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.

What Kind of Tension Should I Use for Knit Fabric?

For instance, if you choose stable knits or loftier knits, it is best to use a lower tension like a 2 or 3. However, if you are using good heavyweight knits, use a moderate tension of around 4. For moderate weight knits, you can go for tension weight between 4-5.

These tensions are considered to be the best and yield excellent results.

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 we shall list some of the detailed descriptions that will help you choose better and sew easier.

– Jersey

The Jersey knit fabrics are the most familiar types of fabric that you will come across. A majority of the t-shirts that you buy are crafted with these fabrics.

This material is the perfect option for comfortable wear. You can stitch t-shirts or blouses with the fabric.

– 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. Furthermore, the material is sturdy enough; hence you can’t damage it easily.

Also, they are easier to handle. 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.

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.

#2. Stitches Type You Make for Your Sewing Projects

We all know that knit fabric is stretchy. Also, there are different types of knit fabrics that you can find.

To make your sewing project a success, you can try several stitches. Especially with knit fabrics, the kind of stitches you sew need to stretch.

Else, there are chances of them popping or breaking. Hence, we shall list some of the basic stitches to try on the knit fabrics to look interesting and stunning.

– 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 the purpose. 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 project is to know your fabric well. It is recommended that you start your projects with thick fabrics.

This is because thick fabrics are easier to start sewing with. You can change your stitches anytime and correct them. Besides, also do take note that every knit fabric is different. Hence, they stretch in different patterns.

Before you work on any fabric, know it’s 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.

#2. Needle

Knit fabrics have fiber in them, which can be damaged if you use regular needles. The regular needles have a sharp head that can damage the look of the fabric. It is also important to note that the knit fabric has a thicker structure.

Hence, the traditional needles may not be the best pick for sewing. It is best to use ballpoint twin needles for sewing knit fabrics. These needles do not have a pointy head, which makes them a suitable choice for knit fabrics.

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 needle for better stitching results, the thread also plays an important role in delivering an excellent finish to the project.

You can not use just any thread for sewing on a knit fabric. On the other hand, the best alternative is to use an all-purpose thread. Several kinds of stretchy threads are easily available in the market. You can choose the best kind of fabrics to suit your needs.
