Sew together is a needlework technique which involves creating small zigzag stitches in order to securely join two material pieces together. This approach adds durability and prevents the fabric from fraying. The join together can be used for a selection of sewing projects, like sewing the hem, stitching patches, or even creating coverlets. It provides a neat and expert look for the completed product.
