i have always used warm & natural, and when I wash it, I do get a wrinkly look, but I like that look. I don't use a poly batting, don't like the way they feel.
I am currently working on my first quilt w/ the Dream Cotton Request because it says it's light-weight. I saw that it said only 1% shrinkage, and I will be real curious to see how this looks after I wash & dry it when I'm finished.
