How to choose your serger

A real necessity for an experienced sewer, or one who is learning, the serger complements the sewing machine. It improves the quality of creations, and makes it easier to achieve professional quality finishes. It cuts the fabric and overstitches it. To help you choose the best serger model for you, here is some useful information.

#1 - The number of coils and points

The overlock machine uses several spools of thread (or cones). Depending on your needs, you can choose between a 2, 3, 4 or 5 spool serger. The number of spools determines the number of stitches you can sew with your machine. Be aware that a good serger should be capable of 4-thread overlock, 2-thread or 3-thread overlock, rolled hem and flatlock.

#2 - Easy to put on

The degree of ease of threading can vary from one model to another. For more comfort and speed, choose a model with automatic threading and tension adjustment. This way, you spend less time adjusting your machine throughout your sewing project.

#3 - The possibility to deactivate the knife

A serger with a removable knife offers more freedom in completing your tasks. You only need to disable the knife during certain operations to avoid cutting the fabric.

#4 - Adjustable thread tension


quality serger should allow you to adjust the tension of the threads independently from each other thanks to the tension discs

, depending on your needs. And this, taking into account the type of fabric, the stitch, or the thread used. A color code allows you to differentiate the tension adjustment knob from one thread to another. Depending on the model you choose, you have the choice of manual or automatic thread tension adjustment on your machine.

#5 - Noise level

Although an overlock machine always makes noise, there are models that are quieter than others, providing less discomfort in your task.

How to maintain a serger?

The best sergers 1

In order to get the most out of your serger and to use it as long as possible, it is essential to maintain it regularly. To do this, take your vacuum cleaner and remove all traces of dust from the machine. Then, use a paintbrush or a compressed air canister, which you can find in a computer store.


First, unplug your machine. Then, using a cloth, dust the outside of the machine. Open the front and side covers of the serger. Unscrew the 2 needles on top and the 2 hooks on the bottom. Make sure the presser foot is up throughout this first step. After that, use a brush to clean all the nooks and crannies and every component of the serger.


Still using this clean, dry brush, proceed to oil all the moving parts of the serger. Don't forget to turn the wheel so that you can access all the components of the machine: pistons, pivots, presser foot, needle arm, grippers, knife, etc. Once the oiling is finished, turn the wheel for a few moments, with the presser foot still raised, to ensure that the oil circulates properly.

Leave it overnight so that the lubricant spreads and flows everywhere. The next day, manually run the machine empty and without thread by running fabric under the lowered presser foot. This is to remove any excess oil from the needles, presser foot and feed dogs. Make several passes until the fabric is no longer stained. Finally, clean the needles with a dry cloth.

The different types of overlock machines

Depending on your needs and expectations, discover the types of sergers to better understand their features and their specificity.

3 or 4 thread overlock machine

This model allows you to sew like a professional. Almost complete, it offers many variations allowing the user to work with 2, 3 or 4 threads. In addition, its differential will allow you to sew and overlock all types of fabrics

, from the thickest to the lightest. Less expensive than other types of sergers, you will appreciate its clean finish on the inside seams.

Although this type of serger does not fray the fabric, it is relatively noisy. In addition, it has few stitch options. This model is ideal for beginners who want to give their work a perfect finish, but can also be used by professionals to serge, join and cut fabrics at the same time.

3-thread overlock machine


model is mainly used for cleanly surfacing the edges of fabrics, but without joining 2 pieces together

. It is recommended for processing thin fabrics. Its ease of use and neat finish are its main advantages. On the other hand, it is impossible to work on stretch fabrics. The machine cannot make decorative stitches. This model is suitable for those who only want to overlock.

2, 3 and 4 wire machine


serger offers the user a huge variation of finishes, since it can do lots of different stitches like 2-thread overlock, 2-thread rolled, 2-thread flat lock

... You will be able to save the threads to use. It also guarantees very discreet finishes and can integrate some automations (like automatic needle threading for example). Easy to use and maintain, the device has many features: pressure adjustment, precise tension settings, etc.

On the other hand, some models are difficult to transport because of their heavy weight. Requiring a good grip, the 2, 3 and 4 thread machine can be used by beginners as well as experts.

Combination overlock machine

This top-of-the-line model offers many possibilities with an almost professional result. Not only does it guarantee the same stitches as the 4-thread overlock machine, but also performs cover stitches and chain stitch. The 5-thread safety stitch combines a 3-thread overlock and a chain stitch seam. In addition, it saves space in small spaces.

Switching from overlock mode to overlock mode and back again requires several manipulations, including threading the loopers and needles, which can be discouraging with regular use. The use of the combination serger is mostly attributed to sewing professionals.

Good to know

Overlocker or sewing machine?

Overlock machine

A serger is used for serging and joining while a sewing machine is used for sewing, although some versions of sewing machines have an option to serge just like the serger. However, the sewing machine is not capable of providing the finishing work that the serger is designed to do. Nor can the serger replace the sewing machine, which has many stitches.

Sewing machine

The sewing machine is ideal for beginners. This is not the case with the serger. Indeed, the main function of a sewing machine, whether classic or more modern, is to sew with straight stitches. In addition, this type of equipment offers the possibility of making various other stitches such as zigzag stitches, decorative stitches, buttonholes, multiple zigzag, invisible stitches or super stretch straight stitches. You can even attach zippers by simply changing the presser foot. Please note that the number of stitches and programs may vary depending on the model.


To conclude, if you are new to sewing, invest in a sewing machine, as it is more affordable. As for the serger, it can be bought after you have purchased a sewing machine. Indeed, the serger works in complementarity with the sewing machine, if you wish to go further in your creations.

Why buy a serger?

A clean finish

The serger gives you the possibility to save time when sewing. It cuts, stitches and overlays the fabric in a single pass. You no longer have to do these tasks individually as you would with a sewing machine.

For sewing stretchy fabrics

Some types of fabric are simply not suitable for a sewing machine, such as jersey, voile or knitwear. These materials can stretch and fray easily. You can use the stretch stitch or the rolled hem to obtain a perfect finish worthy of ready-to-wear clothing.

For speed

As mentioned above, the serger is a multifunctional machine that allows you to save a lot of time. Whether it's a 4 or 5 thread machine, you'll have plenty of time to stitch, serge and trim the excess fabric in one go.

Solid stitches

Unlike a sewing machine that only does zigzag stitches, the serger offers relatively strong loop interlacing.

A great alternative to a sewing machine

Although it cannot completely replace a sewing machine, the serger can be a great alternative. Models with 3 bobbins have the ability to straight stitch and overlock the fabric simultaneously.

The best brands of overlock machines

In our opinion, the best brands of overlock machines in 2022 are :


This year, the famous German brand PFAFF has beaten all its competitors to the top spot in the world of sewing machine manufacturing. This is due to the high quality and reliability of the products and the memorable product experience for the user: with the purchase of a serger, transport handles, waste bin, thread spools and presser feet are offered.

Toyota is a Japanese brand that is not only known for marketing cars, but also high quality sewing machines. Highly appreciated by sewers, Toyota sergers honor the brand's motto: design and functionality.

Founded in 1908 in Japan by the Yasui brothers, Brother is a world-renowned brand that offers sewers of all levels a plethora of overlock machines that can be adapted to their needs and desires. The most popular are the Brother M1034D overlock machine with its complete accessory kits, the Overlock 4234 D with its elegant weaving and quality of workmanship, and the 1034DX with its simplicity of use. What is most appreciated at Brother is its excellent after-sales service and the small training CDs included in the delivery package that serve as instructions for the machine.

Janome is a leading Japanese brand whose main strength is the innovative concept on which it bases the design of its machines. The great thing about a Janome serger is that it is easy to use, it accompanies you all the way and ensures that you are never short of ideas, as its performance and many features encourage creativity and innovation.

With its 165 years of know-how, the Singer brand remains a reference in sewing machines, embroidery machines, overlockers and sewing accessories. Faced with tough competition, Singer manufacturers have adapted the design and options of their machines to appeal to a wider range of customers and satisfy all budgets: a change that has pleased consumers.

The wire must run freely into the wire path of the machine.

Make sure that both threads of your serger (the top and the bottom) have been threaded correctly. That they are not tangled or caught somewhere along the way. When the threads unwind unevenly on the serger, it often results in uneven stitch formation, possible thread breaks, and even needle breakage.

Invest in high quality surfacing wire


tempting as it may be to grab those thread cones still on sale at your local sewing store, we recommend getting higher quality threads. High quality threads are not only smoother, they also have less lint, which means your machine will stay cleaner!

Save thread by spinning your spools.


top looper is the system that uses the most threads, followed by the bottom looper. So make sure the threads are coming out of all 4 cones at about the same time. Switch them around from time to time, switching the needle cones with the looper cones for example. This should keep you from having to make unexpected threads!

Watch out for the needles!


a pin while sewing is never a good thing, but it's especially annoying on an overlocker. It only takes one pin to damage your machine's knife to the point that it needs replacing, and you run the risk of jamming the machine. Not only that, but because the knife moves up and down quickly, the pin is likely to fly at you and hurt you.

Clean your machine regularly.


the serger cuts the fabric while sewing, it accumulates a lot more lint and dust in that sense. It is therefore important to clean it on a regular basis. In fact, most of these machines come with a small lint brush that you can use to clean them.


What is the best serger?

The best serger depends on your needs and budget. Read our buying guide for the best products available.

What if my future serger breaks down?

Search online by typing in the service notice of the brand concerned or of the store where you bought it to get an idea of what to do if your machine breaks down.

What should I do if I have a problem putting on my boots?

This is the most common problem with the serger. Start by unthreading everything. Remove the thread spools completely. Take the instructions, and start from the beginning. If the problem persists, contact an expert to help you.

Is the use of a serger mandatory?

A serger is not required. A sewing machine offers easy stitches such as zigzag stitches, folded seams and English seams. However, if you want to achieve a perfect finish, it is best to use one.

Why choose an automatic threading model?

The automatic threading option is very convenient for those with visual acuity problems and those who do not wish to break their heads following the threading instructions. It is usually done via an electric air pump.
