Strengthen and shape your waistbands with the Fuse and Fold interlining (also known as waist-shaper)! The slots indicate where to stitch and where to fold, to create crisp, strong and neat waistbands. Simply place the adhesive side onto your fabric, cover it with a thin cloth or press paper, and iron on the tape to your fabric. Let the glue set, and you are ready to fold and stitch.
