Best Self  Threading Serger Buyers’ Guide

 Do you wish to upgrade from basic sewing to using a serger, or are you planning to make the first purchase? I know by now the purchasing process must be causing your head to tumble around. In this detailed guide, you will find all you need to consider before taking the next step. You will also find many other facts and tips that will be reliable when looking for the best self threading serger.

  • Rugged construction. The units have a robust structure that allows them to handle the job site toucher.
  • Compact and lightweight. The compact designs provide ease of storage and transportation to different workstations.

  • They allow for stretchy clothing movement.

Types of Self Threading Serger Machines

Below I will briefly take you through the two main types of self-threading sergers available on the market.

  • Lay-in Threading Technology Sergers

 These kinds of sergers only thread the lower looper. If you compare this capability to the standard sergers, you will realize that it’s a remarkable improvement that will make the threading process a lot easier. What makes threading the lower loop easier for you is the machine’s color-corded route that indicates how you should place the thread. Sergers incorporated with this technology are pocket friendly since they have fewer options.

  • Jet Air Threading Technology Sergers

 If you are a seasonal sewer, you will agree that sergers integrated with the Jet air technology are completely automatic self-threaded. Such units utilize the airflow that makes the thread flow through the tubes connected to the threading ports. The air does its trick, and the upper and lower loopers get threaded. Even though such models are a bit pricey, you can never regret having one of them since they compensate the price with incredible features. One of the main advantages of such a unit is that it simplifies the serging process a lot. Therefore, suitable for both professionals and beginners.

Brands that Manufacture the Best Self Threading Sergers

From the reviews of the sergers above, you have seen that the leading brands in manufacturing these units include Juki, Janome, and Elna. However, there are sewing companies that needed to add these types of sergers to their collection. This includes Brother and Babylock. With all these big names, you will discover a variation in price, features, abilities, and other contrasting facts. But for now, the most popular and reliable brands are Juki, Janome, and Elna.

How Does a Self Threading Serger Work?

Using these units is going to be your best experience ever. The reason is that they take care of the entire threading process by themselves. The only thing you need to concentrate on is ensuring the thread seats in the right place. Here is how these machines work.

  • The first step is placing the thread in the guide. This feature will help feed the thread to the lower looper.
  • Once you ensure the thread is secure in the guide, it’s now time to turn the machine on. After this, the lower looper will begin threading itself. Since you will be required to work with the correct tension, you can adjust the thread’s strength by lifting or lowering the presser foot.
  • After the machine is done serging, you should ensure the thread is slack before removing it. After this, you can now turn off the unit and slowly pull the thread out by hand.

How Self Threading Sergers are Different from Normal Sewing Machine

Serger machines are more complex in design compared to standard sewing machines. There is only one similarity between these two units, and the resemblance is that they both sew fabrics. Sewing machines are ideal for almost all sewing applications. On the other hand, sergers can only do specific sewing tasks. For instance, you cannot use serger machines for topstitches and zips.

When you consider cutting your fabric before sewing, you realize that serger machines become reliable since you can use them for cutting and sewing. They integrate blades that sit just before the needle, which stitches. Standard sewing machines typically use one stitch, while the serger uses approximately 3 or 4 stitches. Thus, they can create lock stitches.

Another advantage of using the sergers is that they have a faster cutting and sewing speed than the standard sewing units. The unique fact about these products is that you can join them together into one machine, but this depends on your preference.

Factors to Contemplate When Choosing The Best Self  Threading Serger

  • Number of Threads and Needles

You need to consider the thread capability of your machine before purchasing. Most of these units have a 3 or 4 capacity that requires either two needles and three or four threads. You will also find some with 5 thread capability, although they are not very common. Such units are complicated to thread, but you can bank on them for the strongest and safest stitches. Another point of contemplation is that you can only achieve a cover stitch with a machine with at least five threads. Therefore, always consider the number of threads before purchasing.

  • Differential feed

Almost all sergers come with an adjustable differential feed. This feature will enable your machine to work best with different fabrics of various thicknesses and textures. The differential feed facilitates even feeds on different fabric types. Therefore, it’s of more benefit when working on projects with complex stretch fabrics. It prevents your materials from stretching and losing their original form while sewing. Even more, it enables you to create decorative designs such as ruffles.

  • Adjustable knife

Another noteworthy feature is the adjustable knife. It allows you to achieve quality, clean, and even cuts even on multiple layers of fabrics.

  • Presser feet

This feature is ideal for holding down your fabric while serging. Machines with more presser feet are versatile and can effectively work on different fabric types of varying thicknesses and textures.

  • Speed

All serger machines operate with speeds measured in stitches per minute. The best thing about these serger machines is that they work at relatively high rates, with the standard ones ranging between 1200 SPM and 1500 SPM. I would recommend choosing a product with an adjustable sewing speed since you can easily control your serging speed.

  • Stitch patterns

Most of these products come with multiple stitching options that you can choose from. However, the most basic ones include rolled hemming, flatlock stitching, a 3-thread narrow overlock stitch, and a lettuce edge hemstitch. It would be best if you choose the machine with more stitching patterns for more versatility.

  • Color-coded threading

 Unfortunately, not all the self-threading sergers have automatic threading. However, you can counter this with comprehensive color-coded threading of lay threading.

  • Size and weight

 The weight and size of your machine determine its portability. Therefore, if you prefer a product that you can quickly move around with, consider a compact and lightweight one. This also allows for easy storage.

  • Automatic/adjustable thread tension

 Working with automatic features like the thread tension will allow you a high level of control when serging. This function automatically detects the type of fabric you are working on and immediately adjusts the thread’s strength accordingly. The only drawback is that it might sometimes be challenging to use when working on decorative projects.

Therefore, it would be wise to consider the factors and tips that I have listed in the buyer guide section.
