I've always used Warm and Natural for my quilts. Yes it is wrinkled out of the package, but smooths easily and you CAN fluff it in the dryer.
Recently I tried to "save" money by switching to another brand. It was $39 (Can)for a king sized bat vs $69 (Can) for a queen sized W&N.
BAAAAAAAAAAAD move. This new stuff is soft, but it's so thin and stretchy that to try and smooth it, your hands create stretched areas. I tried to use it on my quilting frame, and I couldn't even TOUCH it to smooth it or it would stretch.
I'm back to W&N. Battered, but loyal from now on.
