Best overlocker sewing machines

Welcome to the wonderful world of overlock sewing machines! If you’re enjoying making your own clothes, but finding your usual sewing machine needs a helping hand at times, it could be time to treat yourself to an overlock sewing machine – also known as a serger sewing machine. They’ll speed up your hems and seams and give your me-made wardrobe a professional finish.


Once you’ve got your sewing kits for beginners sorted and caught the dressmaking bug, now could be the time to think about buying a overlock sewing machine. We’ve gathered some of the best overlockers on the web for you to purchase and add to your craft room!

These nifty machines, trim the seam as you sew, enclosing the raw edge of the fabric inside a thread casing. We’ve been eyeing them up every time they appear on The Great British Sewing Bee for a while now, so we asked our inhouse dressmaking pro Roisin McKenna – Technical Editor for Simply Sewing magazine  – to talk us through what to look for in an overlock machine, and to share her tips for the best serger sewing machines out there.

What is an overlocker?

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.

Best overlocker and serger sewing machines


Jaguar Starter 098 Overlocker sewing machine

Ideal for: Beginners on a budget

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). The machine has a differential feed setting which allows you to control the amount the machine stretches, or gathers your fabric as you sew.

Brother M2104D Overlocker

Ideal for: Beginners looking for a simple, quality overlocker

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 flat bed 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.

Janome 8002DG Overlock machine

Ideal for: Beginner – intermediate, Janome fans

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 – 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.

Useful features include colour coded threading guides, adjustable stitch length and cutting width as well as a fast lower looper threading system. The plastic bed (side) of the machine is removable to allow you to have either a larger flat surface for overlocking or to have a smaller free-arm, ideal for finishing trouser or sleeve hems. The machine also comes with a handy accessory kit including tweezers (helpful for threading), spool caps (stops your thread spools from moving around as you sew), a screwdriver, cleaning brush and four machine needles to get you started!

Jaguar Overlocker Advanced 099

Ideal for: Intermediate level sewists who will make use of the additional presser feet

This Jaguar machine stitches an impressive 1300 stitches per minute!

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. This is an affordable machine that looks great and performs well with everything a dressmaker or homewares maker would need at this pricepoint.

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.

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. Your 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 the different colour.

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.
