Starch shrinks fabric. Well, I'm actually specifically using the Bounce spray. Dangit! Now I know why my pieces seem that I've cut them wrong! I have NOT cut them wrong! What I did was to cut them, then starch and press them. On one dark fabric with little circles on them, I finally saw why it was coming out smaller... the darn stuff actually shriveled right before my eyes!!
SO, lesson learned is to starch and press BEFORE cutting!!!! :o(
