Extra Lightweight Fusible/Iron On Interfacing This is a non woven interfacing it has a little stretch in one direction and has a smooth finish. Tips for use: Cut 2- 5mm smaller than your pattern piece on all sides. Lay glue side (rough side) down on your fabric piece, put a pressing cloth over the top. Place (no steam) iron on top with firm pressure for 10-16 seconds. If the pattern piece is bigger than your iron plate, lift and place your iron this way until all parts of the interfacing have been fused.
