HEATNBOND UltraHold is a heat-activated, double-sided iron-on adhesive sheet for no-sew bonding in appliqué, crafts, and home décor. This pack includes one sheet that is 17 in wide and 1 yd long (43 cm x 1 yd) on a paper backing so you can trace and cut shapes before fusing. Use a dry iron at the recommended setting, press firmly, and let the project cool completely to set the bond Test on a scrap first for best results.
