The hem stitch is a decorative sewing technique used to finish the edges of fabric. It creates a neat, secure hem while adding a subtle design element. This stitch is often used in various sewing projects, including garments, table linens, and curtains. To create a hem stitch, the fabric is folded over to form a hem, and small stitches are taken through the folded edge and the main fabric. This method not only prevents fraying but also provides a polished look. The hem stitch can be done by hand or with a sewing machine, making it versatile for different skill levels.
