Stitching threads are a type of thread which is made especially for use with overlock stitches. These are used for performing overlock stitching. This kind of stitch is frequently used to close seams or finish the edges of clothing. A strong, resilient synthetic material that can endure the high speeds and pressures of an overlock machine is typically used to make overlock thread. When stitching knits, the three-thread overlock seam is most helpful. Woven fabrics can be sewn with stitching threads. The three-thread can be used to finish cloth edges, create thin rolled hems, and stitch pintucks.
