Vilene F250/305 iron-on standard Interlining Firm
1 metre x 0.9 metre wide.
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 interfacing for approx. 8 seconds.
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.
