My word, Warm and Natural is so heavy in one layer as it is, I can't even imagine sleeping under or trying to fold a quilt with 2 or 3 layers of it!!
I use Hobbs brand wool or Quilters Dream wool. Both are less dense, much less heavy, and much easier to quilt through -- hand or machine -- than W&N, in my opinion.
I don't use polyester batting any more because it doesn't breathe, causes body to overheat, and is slippery when trying to quilt.
