Fusible tape is perfect for seams and hems, trims, crafts, and zippers. Steam-a-seam 2 double stick has the pressure sensitive on both sides which allows for a temporary hold to both materials. You can hold your project vertically and the appliqué pieces stay in place and are still repositionable until fused with an iron. Before fusing, tack your project to a wall or try on a garment to check appliqué placement. You're able to reposition pieces while you're wearing them. Once fused the bond is strongly secured. Made by the warm Company, newly designed and packaged.
