Lightweight, nonwoven white ironon fusible interfacing. 100 polyester, 20"x 25 yd bolt. Backed by a dry adhesive film that is activated by heat, HeatnBond interfacing forms a nosew bond three times stronger than other traditional fusible web without adding weight or stiffness. With a low temperature and short pressing time, it allows for a wider range of materials to be bonded. There is no seam or pressing cloth needed, and it will not lift or pucker after washing. Machine washable, dry cleanable. FREIGHT INTENSIVE Billable transportation charges for freight intensive items will be the greater of the dimensional weight compared to the actual weight. In addition to transportation charges, freight carriers may assess an additional oversize charge per package.
