I use W&N all the time in all of my quilts. Most have been hand quilted with no issues. I like a 100% cotton batting particularly on children's quilts. I also believe natural fibers (cotton/wool/silk) all remain very warm when needed and not so much when not as the natural fibers 'breathe' vs synthetic fibers. I use the same 2 100% cotton blanket and quilt on my bed year round with no issues beyond my 'personal summers', lol.
