A rolled hem foot is a sewing machine attachment used to create a narrow, rolled hem on the edge of fabric. It is typically used on lightweight fabrics, such as voile, chiffon, and silk, and can be used to create a variety of decorative effects.
Rolled hems are not only aesthetically pleasing, but they are also more durable than traditional hems, as they are less likely to fray or unravel. They are also less bulky than traditional hems, making them ideal for garments that will be worn close to the body.
