A coverstitch machine is a specialized type of sewing machine that creates a professional-looking hem that covers the raw edges of a fabric and retains its stretchability. It is primarily used for hemming knit fabrics and activewear projects. The stitch it creates is stretchy and secure, making it ideal for knit garments that require seams that retain stretch, such as active wear, bathers, and childrens clothing. A coverstitch machine can also be used to add topstitching to activewear and to add elastic to swimwear or activewear projects.

A coverstitch machine is different from a regular sewing machine because instead of a bobbin, it has a looper. This means that the stitching is stretchy and can withstand even the stretchiest of knit fabrics. A coverstitch machine can be used with one, two, or three needles for a double or triple stitched look.

A coverstitch machine is not the same as a serger or overlocker, although you can get combination serger and coverstitch machines. A sergers main purpose is to tidy up seams and prevent fraying, while a coverstitch machines job is to hem finished garment edges or do decorative chainstitching.

If you sew a lot of knit fabrics and are looking for a way to elevate the finish of your garments and avoid popped stitches, a coverstitch machine may be a good investment. However, if youre more comfortable with a zigzag stitch or twin needle, then there might not be a need for you to buy an entirely separate machine.

In summary, a coverstitch machine is a specialized sewing machine that creates a professional-looking hem that covers the raw edges of a fabric and retains its stretchability. It is primarily used for hemming knit fabrics and activewear projects and is different from a regular sewing machine or serger. If you sew a lot of knit fabrics and want to elevate the finish of your garments, a coverstitch machine may be a good investment.
