Whipstitch represents a stitching technique that involves making small in and out stitches in order to firmly connect two material pieces together. This method provides resilience and avoids the fabric from fraying. The join together may be used for a range of stitching projects, such as sewing the hem, sewing patches, or even making quilts. It provides a clean and skilled look for the finished item.
