10 Best Self Threading Serger 2025 in the United States

The Bernette 64 Airlock Overlocker is an impressive machine for those diving into the world of overlocking. One of its standout features is the automatic threading system, which simplifies the often tedious task of threading the loopers. The color-coded paths make this process intuitive, allowing users to thread either looper separately or both at once with minimal effort. This is particularly beneficial for beginners who may feel overwhelmed by more traditional machines. Speed is another strong point of the Bernette 64, enabling users to complete projects quickly. This can be particularly useful for those working on larger sewing tasks. Additionally, the micro thread control feature ensures consistent stitch quality by allowing users to set tension just once, which saves time and reduces frustration during sewing.

Illuminating the workspace with five LED lights is a thoughtful touch that helps enhance visibility, making it easier to work accurately, especially in low-light conditions. The large 130 mm working area also provides ample space for handling bulky projects, which can be advantageous for various sewing applications, including heavy fabrics. However, while the Bernette 64 has many positives, it’s worth noting a few areas that might be limiting for some. Although it is user-friendly, beginners may still need a learning curve to fully master all stitch options and settings. Additionally, while the freearm feature is useful for sewing tubular items like cuffs, some users may find that it doesn't completely eliminate the challenges of more intricate projects.

In terms of size and weight, the Bernette 64 is relatively compact, but at 20 pounds, it may not be the most portable option for those who might want to take their machine to classes or different locations. This overlocker is well-suited for both beginners and experienced sewists looking for efficiency and a reliable performance, provided they are willing to invest a little time in learning its features.

The quick-change rolled hem and adjustable presser foot pressure add to its flexibility and convenience. This serger also boasts an accessible lower looper with a pretension setting slider, making adjustments easier to handle. While it offers adjustable tension settings, some users might find it takes a bit of practice to get used to them.

While the machine has many strong points, it does come with a learning curve, especially for those new to serging. Threading can be tricky, despite it being designed for ease.
