Theoretically, you can use normal sewing thread for your overlock, but special overlock sewing thread such as SERACOR or SERAFLOCK is often the better choice. Overlock thread is particularly tear-resistant and elastic, which means it is designed for the high speeds and special requirements of the overlock machine. Normal thread can tear or work poorly, especially with elastic fabrics or thick seams. In addition, you usually need a lot more thread on the overlock machine than on a normal household sewing machine. It is therefore worth buying overlock sewing thread in large cones, which need to be changed less often even when used frequently.

SERACOR is a universal overlock thread that is ideal for finishing edges due to its high tear resistance and durability. It ensures clean and stable seams on most fabrics. SERAFLOCK, on ​​the other hand, is a voluminous bulky yarn that is particularly suitable for elastic fabrics. It offers soft, stretchy seams and is ideal for sensitive or stretchy materials.

A bulky yarn like SERAFLOCK is used for particularly soft, voluminous seams, especially on stretchy or delicate fabrics. It is perfect for use in the overlock or coverlock machine to create stretchy and comfortable hems and seams - for a particularly comfortable feel on sportswear, underwear or loungewear.
