Thanks, all
Well, I guess I'm going to have to pay more attention when I buy batting. I do some hand quilting (so I shouldn't use skrim) and some machine quilting (so I can use skrim). I do know that I don't like hand quilting with warm and natural. I've done it and it is much stiffer and harder to make the tiny little stitches that I like on hand quilted items.
