Steam-A-Seam 2 is the incomparable fusible web. It has a pressure-sensitive adhesive that provides a temporary hold to your materials. There is no pressing until your entire appliqu? is in place. Position your pieces and they will stay in place without shifting. Steam-A-Seam 2 can be used on all regular to heavy fabrics. Once fused, the bond is strong and permanent. You can machine wash and dry or dry-clean (we do not recommend drying with a dryer sheet). You can also leave the edges unfinished; will not fray or lift. Steam-A-Seam Will not gum up your needle if you choose to stitch through it. 18″ wide, sold by the metre.
