The Buyers’ Guide

Are you looking for a bit more information before you choose the self-threading serger that meets your needs? In our detailed buyers’ guide, we have collected all the things to consider before you buy, and many other facts and tips that will be of good help when you are looking for a machine like this.

Is there a self-threading serger?

Yes, and that means no more hassle of threading your serger manually! Many manufacturers choose to provide their newest serger with a technology called ‘Jet Air.’ With that being said, there are also variants on the market that are equipped with an automatic lower looper threader. It does make the process of threading a lot easier, but it isn’t as complete as the Jet Air technology, where, with one push on the button, your serger is threaded.

Types of self-threading serger machines

Below, we will briefly explain the difference between the two types of self-threading sergers on the market.

Jet Air ThreadinTechnology Sergers

Self-threading sergers that feature the Jet Air technology are completely automatic self-threaded. With the use of air, the threads are flowing through the tubes, to which the threading ports are connected. The air does the trick, in this case, and threads both upper loopers as lower loopers. This model is often a bit more on price, but it is as complete as it could be. As this type of machine simplifies the process a lot, it is a super easy machine to use for beginners as well.

Lay-In Threading Technology Sergers

In contrast to the serging machines that are supplied with the Jet Air technology and thread both loopers in the machine, the Lay-In technology only threads the lower looper. Compared to ‘regular’ sergers, this is already an improvement and is likely to make the threading process a lot easier. What assists you in that is the color-coded route on the machine that indicates which way the thread should be placed. Serger machines that include this technology are often more budget-friendly as they have fewer options.

Brands that manufacture self-threading sergers

As you could see on our reviews list, brands in the sewing industry that manufacture self-threading sergers are Juki and Janome. However, there are a handful of other brands that added this type of machine into their collection, as follows:

  • Brother 
  • Elna
  • Baby Lock

You will discover a difference in price, abilities, and features amongst all of these big names. However, the most popular brands of this moment are Juki and Janome.

What kind of thread do I use for my serger?

Because a serger sewing machine is typically used to finish off the seams of your sewing project strongly, the thread used for it is different than the regular sewing thread. Compared to the regular thread, the type of thread used for a serger machine is finer. This has a number of reasons, including that finer thread is less likely to create bulky seams. The smoothness of it allows the thread through the machine and your sewing project.

What is also important in the serger thread is the amount of lint it produces, or better: what it doesn’t produce, as this can easily clog up the serger. And we all know that’s no fun! Usually, this type of thread comes in large spools or cones and has a quite long length, around 3000 yards. Using normal thread in your serger can work, but as it is not as strong (and more expensive), it is not recommended. Serger thread is made of cotton, cotton-poly, polyester, wooly nylon, or nylon. 

Top tip: for an extra professional-looking seam and finishing on your sewing projects, make sure to carefully pick the color and material of your thread to match it with the fabric color you used.

The Benefits of Using a Self-Threading Serger

Oh, there are many. To us, the three most important and outstanding benefits to investing in a machine like this are:

  • With the right thread and the new jet air technology, the amount of lint that gets built up is significantly reduced, or even impossible. This means a longer-lasting machine!
  • Super easy to use, no matter if you are a beginner or a seasoned sewer; it just makes life so much easier. Threading an overlocker has always been seen as challenging, but not anymore!
  • No more twisted, tangled, or knotted threads. 

How much does a self-threading serger machine cost?

Given the fact that this is a relatively new technology in the market of sewing and serging machines,  it has a price tag to it as well. Of course, it firstly depends on what features you are looking for. A serger that has lay-in technology and is equipped with only a lower looper threader will cost you less than a jet air technology serger. According to us, the best serger is the type with the most features so you won’t have to compromise or use more machines. The price varies from $300 to $1500.

The Takeaway

Self-threading sergers are an invention that we can imagine every sewer to be happy with. With this new technology, anyone that has been dealing with the ongoing struggle of threading their overlock machine manually can entirely and easily skip this step by investing in a long-lasting, strong, and reliable self-threading serger. 

As we discussed above, there are so many reasons to decide to invest in a machine like this, including the fact that this new top of the market machine includes so many other options besides a self-threading feature. They are 100% likely to save you up a lot of time and expand your sewing qualities!

Although it takes some time to find the machine that is right for you, hopefully, our reviews list has helped you already with a step in the right direction. Are self-threading sergers new to you, or are you working with a self-threading serger machine already? Feel free to share your questions and thoughts with us below!
