I think it was the pattern Jumping Jacks that Jenny from Missouri Star Quilt co. working with cotton and flannel. She said not to prewash flannel pre cuts. You might want to watch that videos to see what else she said. I think it was something about holding your flannel up to the light to see if you can see holes. Good quality flannel you should not see holes and the shrinkage will be minimal.
