Best overlocker and serger sewing machines

1. Brother M2104D Overlocker

Best for beginners

Brother 2104D Overlocker Sewing machine

One of the best overlocker machines at the lower end of the price range is the Brother M343D overlock machine. It can finish seams with 3 or 4 threads and offers several stitch options, including narrow hem, rolled hem and ribbon lock stitches.

The side cover of the machine is removable to convert the flatbed into a free arm, ideal for sleeves or trouser hems. The threading system is simple (as overlockers go!) with colour coded thread path illustrations and easy-to-use dials.

See our guide below for the thread and needles to use with overlockers for a balanced, secure stitch.

2. Jaguar Starter 098 Overlocker sewing machine

Best for beginners on a budget

Jaguar Starter Overlocker 098

We’ve started with an overlocker at the lower end of the price range for anyone looking to dip their toes in the water. This overlocker is simple to thread and can stitch with 3 or 4 threads as well as having a rolled hem setting (ideal for finishing the edges of lightweight fabrics).

Next on the list is the Janome 8002DG. Janome is a popular choice for many sewists and this overlocker won’t disappoint. The thread guide is colour coded so you know which thread sits in which position.

This is very useful as threading overlockers can be a chore to begin with, but once you get the hang of it you will be able to thread it in no time, much like learning to thread a regular sewing machine.

Like the Brother and Jaguar models above the Janome 8002DG can stitch a rolled hem and has a differential feed setting to help sew stretch fabrics and fabrics of different weights.

The machine can stitch with 2, 3 or 4 threads as well as a rolled hem setting and changeable differential feed settings. The machine also comes with an accessory kit worth £100!

Presser feet for overlockers can be pricey but this kit contains five feet that will help you sew a variety of fabrics and trims. Included are a 5mm blind hem foot and a 10mm blind hem foot, piping foot, gathering foot and elasticator foot.

The left side of the machine acts as a storage compartment which, when removed, also converts the bed into a free arm, great for hemming cuffs etc.

The standout feature of this machine is air-threading capability. Threading overlockers can be fiddly and for those who would prefer to avoid manually threading the upper and lower loopers this is a great option. If you want to see how air threading machines work pop over to YouTube and watch a demonstration - they’re fantastic!

The machine has many advanced features and would be perfect for anyone who sews for a living or someone who sews a lot on a regular basis. On top of all of the built in features, the solid cast aluminium frame makes this an attractive machine too. And finally we had to give this overlocker bonus points for a built in needle threader – a rarity on overlocker machines.

Best overlocker threads

When sewing with an overlocker you need to use threads that contain more than the standard 100m. Smaller thread spools will run out quickly and could be an expensive way of finishing the inside seams of a dress!

As a rough guide, look for threads that have 1000m minimum for stress-free sewing. You will need 2, 3 or 4 cones of the same colour depending on whether you are using a 2, 3 or 4 thread setting. If possible, try to pick up four cones of the same colour as then you will always be able to work with the maximum number of threads.

If you’re in a bind, use similar shades such as three black and one navy, you shouldn’t be able to notice the difference if you thread one of the needles with a different colour.

Great quality, durable threads which can be used on your sewing machine or overlocker. 1000 metres means you won’t run out mid seam and the threads are available in a wide range of colours, this pack of ten is also available in white.

Best overlocker needles

Just like with a regular sewing machine, overlockers require you to match the needle to the type and weight of fabric you are working with. The universal needle equivalent for overlockers would be the Overlocker Needle. Overlocker Needles have a stronger shaft than universal needles as overlockers sew at a much higher speed.

What is an overlocker?

Overlockers are a type of sewing machine. They're specifically designed to join fabrics together with an overcast/overlock stitch. Overlockers are great for making clothing.

There's a few major differences between overlockers and your classic sewing machines. First is the speed. Typically overlockers can stitch at twice the rate of sewing machines. They also use between 3-5 cones of thread at one time which means they can create lots of different types of stitches.

Lastly, overlockers automatically trim away excess fabric when being used, a function sewing machines can't perform. This saves you time and gives a beautiful professional finish to your peices.

What does an overlocker do?

Overlockers (or serger sewing machines) are used to finish raw fabric edges. They have grown in popularity in the last 50 years since domestic overlockers have become widely available and affordable to the home sewist.

For complete beginners to dressmaking, there are lots of stitches available on a domestic sewing machine (browse our best sewing machines for beginners guide) such as zigzag and overcast stitch. These can be brilliant for finishing raw edges and making sure garments last a long time.

However, many dressmakers are interested in overlockers as they bring a professional level of finishing to garments in a quick and easy manner. As well as producing a series of stitches over the raw edge, overlockers also cut away the raw edge of the fabric as you sew for a neat and precise finish.

You can also use an overlocker to stitch the seam and finish the raw edges all in one go – this means that the time taken to sew and finish one seam can be halved.

Don't forget to check out our complete guide to the best sewing machines for more on what to consider when finding your perfect sewing machine.

How to use an overlocker

Once you've purchased your overlocker you'll need to learn how to use it. We're going to talk you through the very basic steps of using the machine so you can start sewing right away!

Threading your overlocker

First, you need to thread your overlocker. The threading process differs between models so always read the manual.

Threading from scratch

If your machine doesn't have any thread then you must thread through the looper and the needle. Thread each cone one at a time. Start with the upper looper then the lower looper and finally the needle

Threading your looper

1. Find your thread and take it up through the eye on the thread hanger and down into its matching thread guide. This will be on top of your machine.

2. Now take your thread through the tension mechanism and into the thread guide below the tension dial or lever.

3. Your machine will have coloured dots or lines indicating to you which guides should be threaded first. Follow the instructions and take your thread through each, along the threading run.

4. Pull your thread through the eye of the looper

5. Pull the end towards the back of your machine leaving 15cm-20cm hanging free

6. Repeat for every looper, following the corresponding colour-coded runs

Threading your needle

1. The first and second step is the same as threading your looper. Copy the steps above.

2. Grab your thread and take it to the left, under the guide and over the top thread path. Follow the thread run.

3. Slide your thread through the wire guide and through the eye of the needle

4. Pull the end of your thread to the back of your machine and under the foot

5. Leave around 15-20cm hanging free

6. Repeat for the other needle/needles

Threading if your machine already has threads

If your machine already has some threads in place (you're just looking to add more when it's running out) then the knot method is the easiest form of threading.

  1. Use a flat reef knot to tie your new thread to the old thread.
  2. Ensure the pressure foot lever is up
  3. Set the tension dial to 0
  4. Wind your newly tied threads through your machine using the handle
  5. Ease the knotted part of your thread through as they can get caught or stuck
  6. Stop just as the knot reaches the eye of your needle
  7. Snip just before the knot
  8. Thread through the needle
  9. Once you've threaded reset the tension
