First iron the fabrics at length with steam to avoid any shrinkage later on. Allow the fabrics to dry completely. Place the interfacing with the coated side on the wrong side of the fabric. Then cover with a damp cloth and press the iron carefully for about 6 seconds, step by step each area; iron setting: wool. 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.
Care: Washable up to 40 °C in the gentle cycle or dry cleanable
