Fuse-a-web Iron on, adhesive web interfacing for appliqués, handicrafts, and repairs such a hemming. Fuse fabrics and different materials such as raffia, cardboard, wood and leather* together by ironing them using this versatile product. The web is supplied on a transfer paper which allows accurate shapes to be drawn and cut-out. The paper transfer also supports the web whilst ironing ensuring that the web doesn't lose its shape. Each purchase comes with instructions on how to apply the interfacing with an iron. You'll typically have the iron set on a warm iron temperature (2 dots - 150°) to hot iron temperature (three dots - 200°) for up to 10 seconds. We advise trying it out on a test piece or an inconspicuous area first.
