A permanent iron-on interfacing that provides extra crispness. Use to add body and strength to fabrics used for projects such as eyeglass cases, tote bags, hat brims, visors, soft luggage, etc. For areas that require extra rigidity, use two layers. Machine wash warm. Tumble dry low. Always pre-test with a swatch of your fabric before fusing to make sure that it is compatible with the fusible. This non-woven interfacing does not require pre-shrinking. However, we recommend that you pre-shrink your fabric. General Directions: Place shiny adhesive against wrong side of fabric. With your iron at wool/steam setting, press down firmly in place for 10-15 seconds, lifting slightly and overlapping to ensure that all areas are fused. Always use a damp press cloth and press down firmly.
