HeatnBond Ultrahold 10yds x 7/8 in for dark fabrics is much stronger than traditional fusible webs. This low temperature, heart activated, double-sided adhesive, is permanent and will give you edge-to-edge coverage without puckering or bunching. Great for use on fabric, but can be used with a wide range of materials such as fleece, suede, cardboard, leather, and wool. Works best with medium and heavyweight fabrics. Use HeatnBond Ultrahold for all of your no-sew projects. Machine washable.
