A blind hem is a sewing technique used to create an invisible hem on garments, allowing the fabric's edge to be finished without visible stitching. This method is commonly used on skirts, pants, and dresses to maintain a clean and polished appearance. To achieve a blind hem, the fabric is folded and stitched in a way that only a small portion of the fabric is visible on the outside. This can be done by hand or with a sewing machine using a special blind hem foot. The result is a neat finish that enhances the overall look of the garment.
