A quick note back to the original question—Mistyfuse and wool. They're a wonderful matchup and it's been very popular with wool vendors and in wool appliqué. Your needle won't even feel it in there. Mistyfuse is blown into a web so that it is like long, fine fingers. That's how we achieve such a strong bond and stay so flexible. It will reach into and grab onto fibers. The result is a bond that is very strong yet totally flexible and soft and never, never sticky. Mistyfuse has a low temperature melting point but do be sure to give it the time to develop the bond. Don't worry about over ironing—Mistyfuse can take the heat and the time, it's hard to iron it away.
