A serger, also known as an overlock machine, is a specialized sewing machine that creates a clean, finished edge on fabric. It is often used for garments, but can also be used for home dcor, crafts, and more. Sergers use multiple needles and threads to create a variety of stitches, including the overlock stitch, the flatlock stitch, and the rolled hem stitch.
Sergers offer a number of advantages over traditional sewing machines. They can produce a more professional-looking finish, they are faster and more efficient, and they can handle a wider variety of fabrics. However, sergers can also be more expensive and complex to use than traditional sewing machines.
