Things to Consider
Buying the best self-threading serger can be a daunting experience because of all the overwhelming options available. Plus, there is a lot to consider for you to make the best buy. We have compiled all the important tips you need to have before you go shopping for a self-threading serger. You’ll get to know what a serger really is and the features that a good one should have.
What is a serger?
Quite simply, a serger is a type of a sewing machine that binds fabric together with an overlock stitch which is created with 3 or 4 kinds of threads. It also cuts the fabric when binding so that you don’t have to cut your project yourself before sewing like when you’re using a normal sewing machine.
Sergers are much faster and easier to use compared to typical sewing machines and they offer more durable stitches especially for projects like hemming the edges of your fabrics.
Features to consider when choosing a self-threading serger
These are the key features that any good self-threading serger should have:
There are 2 different types of self-threading chargers: one that threads the lower looper only and another that can thread both upper and lower loopers. The one that can thread the lower loop only is usually cheaper because it only automates a single loop.
Sergers with the patented jet-air system are the easiest to thread as they let you insert a certain length of thread in the opening then do the rest of the work for you. A powerful burst of air threads the machine in no time saving you the agony of manual threading.
Number of threads and needles
The thread capability of a self-threading serger is also a crucial consideration. Most sergers have the 3/4 capability that uses either 2 needles and 3 or 4 threads. They are usually durable and suitable for most sewists as they can meet many needs.
Machines with the 5-thread capability are not very common but you can easily find one. They are more complicated to thread but on the bright side, you can trust them to give you the strongest and safest stitch.
Another noteworthy point, is that for you to achieve a cover stitch, you must have a machine that has at least 5 threads. Therefore, you have to consider the kind of serger stitches you want to be producing before choosing a machine.
This is measured in stitches per minute. Standard self-threading sergers sew at an incredibly fast speed ranging from 1200SPM to 1500SPM. Though it can be difficult to keep up with the serger at times especially if you are a novice. In such a case, it is advisable to go for one with an adjustable sewing speed built into the pedal. It allows you to control the speed with your foot.
Nearly all sergers have an adjustable differential speed. It is a must-have feature if you intend to work on different kinds of fabrics with different thicknesses and textures.
Since it allows you to achieve an even stitch on different types of fabrics it can come in handy when working on projects with complex stretchy fabrics like spandex. Your fabrics wouldn’t stretch and lose their original form during sewing. What’s more, it allows you to create decorative designs like ruffles on your fabrics.
Automatic/adjustable thread tension
This is essential because it allows you a high level of control when serging. Unlike other machines that require you to adjust the thread tension manually by pushing a button, a serger with automatic adjustable thread tension detects the kind of fabric you are working on and adjusts accordingly. It works well all the time except when you are working on decorative projects as finding the right tension settings becomes a bit difficult.
This is what holds down the fabric while you are serging. It allows you to work on different types of materials with varying textures and thicknesses. The more presser feet a machine has, the more versatile it is.
Most sergers have multiple stitch options that you can choose from to work on different projects. The most basic ones that you should look out for include; rolled hemming, lettuce-edge hem stitch, a 3-thread narrow overlock stitch, and flatlock stitching. Just like presser feet, the more stitch pattern options a serger has the more versatile it is.
For you to achieve top-quality clean, and even cuts on multiple layers of fabric, you have got to get a serger with a heavy-duty knife like the Juki MO-2000QVP Air Thread Serger.
Instructional DVD and manual
Be sure to go for a machine that comes with a good instructional manual. It will help you cut through the learning curve associated with using a new serger pretty quickly. If you learn best visually, opt for instructional DVDs and if you are okay with reading, then go for the written instructions. Just keep in mind that a picture speaks a thousand words.
Size and weight
This determines the portability of the machine. If you want a machine you can easily move around then choose a lightweight and compact unit like the Baby Lock Celebrate Serger Machine.
Not all machines have automatic threading but a comprehensive threading guide like color-coded threading of lay-threading comes is really helpful.
Any serger with multiple features and basic functions that make it user-friendly like differential feed, automatic adjustable thread tension, threading guides and clear cut instructional manuals are good for beginners.
