Lightweight interlining with some stability for small parts of blouses and dresses. Ideal for use on lightweight fabrics such as cotton and polyester. Simple to iron on. Comfortable to wear. Flexible feel. To use, place the interfacing with the coated side on the wrong side of the fabric. Then using dry heat glide the iron firmly 5 6 times very slowly over each area, so that each area receives approx. 8 seconds of heat. Iron setting: silk wool. Allow the pieces to cool flat for about 20 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.
