Change your mind at any time! Your favorite just got better. Nothing is permanent until pressed with an iron. If you change your mind about the appliqué fabric you are using, simply peel off Steam-A-Seam and stick it to new fabric. Since you haven't fused Steam-A-Seam to your applique material, you can remove it from your fabric scraps and use both the excess fabric and Steam-A-Seam for other projects. There is no waste. Steam-A-Seam 2 Double Stick has the pressure sensitive on both sides which allows for a temporary hold to both the appliqué material and the background material. 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 the same as the original Steam-A-Seam.
