Firm, stable interlining for shaped cuffs, shaped belts and for textile craftwork. Guarantees durable shape. Ideal for lightweight to medium weight fabrics such as cotton. Simple to apply. Long lasting shape. Also washable at higher temperatures. To apply, 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 of the insert, so that each area receives approx. 8 seconds of heat. Iron setting: 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.
