Description
Pellon SF101 Shape-Flex is the ultimate all-purpose, woven fusible interfacing for apparel, quilting, and craft projects. Made from 100% cotton, SF101 acts as a “second skin” for your fabric, providing essential crispness and support without changing the natural look or feel of the material. It is the gold standard for stabilizing T-shirt quilts, reinforcing collars and cuffs, and adding body to handmade bags.
Unlike non-woven interfacings, Shape-Flex has a woven grain that moves with your fabric, ensuring that your projects remain flexible yet structured. It prevents fabric stretching and distortion during sewing and is exceptionally easy to apply with a standard steam iron. Whether you are a garment maker or a quilter, SF101 is a “must-have” staple for your sewing room.
