Use Clear Plexiglass!
Use a piece of clear plexiglass or acrylic to test out your quilting designs right on your quilt top! You can get it at most hardware and crafting stores. It's not too expensive and lightweight. Use dry erase markers and a piece of batting for erasing. Be sure and tape the edges with a bright color painter's tape or duct tape so you don't go past the edges and mark on your top.
