I belong to a paint club too and every year since I can remember (way back in the 70's) we've raffled off a quilt at our fall craft show called Kris Kringle. The blocks have always been hand painted by our members and they have always been absolutely BEAUTIFUL!!! You can buy acrylic fabric paint or there's a medium that you can purchase to put in regular acrylics to make them fabric ready. If you use regular acrylics without adding the medium the fabric will be REALLY stiff. The medium or the fabric paints are very soft and pliable. Read up on it, there's plenty of books available on the subject and probably tutorials, utube videos and everything else. Acrylic wall paint and acrylic paints are NOT the same thing. Look for Deco Art, Plaid, Ceramcoat, or something along that line in your local Micheals, Joann's, Hobby Lobby or even Walmart has a few. Just make sure that if they aren't fabric paints you add the medium. You might also want to practice on a few pieces to know just how to do it. It's usually a "no or very little water added" project. You also need some good stiff fabric brushes. They usually have stiff white bristles.
