5 Best Self-Threading Serger

Threading a serger sewing machine has always been one of the most important topics in the sewist world. While operating a serger initially you will have to thread the machine before you can start working on your project. A self-threading serger helps you reduce this frustrating feature so that you can focus on your stitching.

A self-threading serger is not just for beginners but also saves a lot of time and mental peace for professionals. Some high-end automatic threading serger is a bit expensive but not all of them fall under that range. There are so many affordable sergers in the market that can automatically thread themselves.

How Self-Threading Sergers Work

Have you ever laid down the thread on a threading guide and flipped the switch to confirm it? if yes then the exact thing is done by the machine engine when they thread the lower loopers.

Now the complex and time-consuming work is to thread both the loopers. Modern sewing machines are equipped with jet air technology, which enables a user to finish this complex work without any hassle.

Pick your favorite serger thread and get on the machine to thread it fast.

You will find the fixed length of thread that you have to place in the opening for the machine to automate the process. The entire process will be mentioned in the serger manual for each brand which will make it even easier for you to thread your serger.

Types of Self-Threading Sergers

Self-threading machines are the easiest serger to thread and which is why you must understand the automation behind its option.

You will find two different types of self-threading sergers to choose from.

The most common type is the one that only threads lower loop, and they often cost cheaper because of being able to automate only one loop.

Another type of serger is able to thread both lower and upper loopers. You will read about Juki MO-1000 using Jet Air for the process that makes the threading process much easier.

Any good self-threading sergers let you insert a fixed length of the thread in the opening and the rest of the work is done by them.

Sergers are known for their fast speed so obviously, you can not expect it to be a pin-drop silent machine. However, let’s say you are stitching in the corner of your room then it is not going to disturb anybody watching TV in the room itself.

Read Customer Reviews Here »

If you are looking for a mid-range portable serger then you can try Elna 664 Pro Overlocker. It is built with perfection and runs at a top speed of 1,300 stitches per minute.

Thanks to its quiet operation it became very popular among beginners.

Its 4-piece dog feed system is capable enough to help you sew through thick fabrics and can handle sensitive fabrics too. In addition to that, it also features adjustable cutting knives for smooth edges.

Many sewists like Elna serger because of its quiet operation and wide range of stitch operations.

Elna 664 comes with a pre-tension setting lever and it is one of the best self-threading sergers from this brand. However, I personally don’t like it because of its limited applications.

Brands That Manufacture Self-Threading Serger

Though there are too many brands that make really good serger sewing machines, not all of them are able to introduce self-threading features.

In this review, our effort was to give you the most trusted sergers option to choose from. Because even top brands failed to simplify the complex process of threading.

Here are some of the top brands that build automatic threading sergers.

  • Juki: It is the most trusted brand when it comes to self-threading machines.
  • Janome: With the launch of MyLock 634D, Janome becomes the next popular sewing machine brand after JUKI, brother, and Baby Lock.
  • Baby Lock: Though BabyLock machines are expensive they definitely do the job right.
  • Brother: Though Brother sewing machines are top-rated, still they have not launched any really worth-the-money self-threading sergers. (We think they will in the future)
  • Elna: I have placed Elna below Brother only because of the Less Popularity in the brand. Otherwise, the Elna 664 PRO Overlocker can beat any brother serger when it comes to self-threading.

Wrapping Up

Threading takes a lot of time and even after lots of practice and a color-coded guides we tend to make mistakes. This is why I think considering buying a self-threading serger.

Automation of this complex process is going to help you save a lot of time. You can set up your entire work layout quickly and are less worried while you stitch or roll hems.

Self-threading can be definitely time-saving but if you are a beginner I would recommend you to learn the manual threading process. Then go for the automatic things. Because when you combine experience with updated technology, you tend to sew the most creative dresses and produces superior finished garments.
