A blind hem is a sewing technique used to create a nearly invisible hem on garments and fabrics. This method involves folding the fabric edge and stitching it in a way that the stitches are hidden on the front side, making it ideal for hems on skirts, pants, and curtains. To achieve a blind hem, a special blind hem foot is often used, which helps guide the fabric while sewing. This technique can be done by hand or with a sewing machine, providing a clean finish that enhances the overall appearance of the finished item without visible stitching.
