This Pellon® SF101 Shape-Flex® will help to shape your materials and clothing. The interfacing provides crisp support for collars, cuffs, yokes, pockets, facings, and other areas of a garment that need details. The all purpose, woven, fusible interfacing can add stability and body when used as a backing for needlework and punch embroidery. Shape-Flex® is intended for light to medium woven and knit fabrics, including oxford cloth, chambray, gingham, madras, tattersall, pincord, flannel, and polyester/cotton blends. This interfacing is machine washable and sewing machine safe.
