Sew together represents a stitching technique which involves making small in and out stitches in order to securely connect two material pieces together. This approach adds durability and stops the material from fraying. The backstitch is used for a variety of sewing projects, like finishing the edge, sewing patches, or even creating coverlets. It offers a neat and professional look for the final item.
