Backed by a dry adhesive film that is activated by heat, HeatnBond interfacing forms a no-sew bond three times stronger than other traditional fusible web without adding weight or stiffness. Craft Weight interfacing is an iron-on, fusible, non-woven interfacing that is stiffer and is used primarily for craft projects such as wallets, handbags, and home décor. With a low temperature and short pressing time, it allows for a wider range of materials to be bonded. There is no steam or pressing cloth needed, and it will not lift or pucker after washing. Machine washable, dry cleanable. 100% Polyester.
