Difference Between Chain Stitch and Lock Stitch
What is Chain Stitch?
The stitch which is formed by two or more sets of sewing thread (needle thread and looper thread) is called chain stitch. Here, threads are bound together by interlacing and looping. It should be noted here that, chain stitch strength is greater than lock stitch, and back tacking is not needed at the finishing side of the stitch as security.
