A rolled hem is a sewing technique used to create a narrow, finished edge on fabric. This method involves folding the fabric edge over itself and stitching it down, resulting in a clean and delicate finish. Rolled hems are commonly used on lightweight fabrics like silk or chiffon, where a bulky hem would be undesirable. This technique can be done by hand or with a sewing machine, often using a special presser foot designed for rolled hems. It is popular in garments, table linens, and other textile projects, providing a professional look while preventing fraying of the fabric edges.
