depending on how much pucker you want in your quilt, I soak my batting in warm water then spin DO NOT AGITATE I lost one by forgetting! Then put it in the dryer, then lay it out on the extra bed, you still get enough shrinkage to look like an old quilt, if you don't want to preshrink it just toss a damp bath towel in the dryer with it on warm for a few minutes then lay it out, any fold marks that remain will easily disappear once you get it on the frame
