Interfacing deal for pelmets & tiebacks, fabric bowls, bags, belts, hats and other creative works. Suitable for almost all fabrics. Washable and dry cleanable pelmet interfacing. Smooth, fabric look. Retains shape. Comfortable to iron on. To use, place the interfacing with the coated side on the wrong side of the fabric. Then cover with a damp cloth and press each area for about 15 seconds, being careful not to move the iron. Allow the pieces to cool flat for about 30 minutes, so that the adhesive can set properly. We strongly recommend that you attach a small piece of interfacing to a fabric remnant with your iron first to make sure that the hold and the adhesion meet your expectations.
