Hobbs cotton with scrim is less dense and less heavy than Warm and Natural.....which, to me isn't all that natural in a finished, long-arm quilted, queen quilt. I hate trying to fold mine, my shoulders ache afterwards. it's the only personal quilt I have with WN batting and the one I like the least.
I personally much prefer, for weight and drape, Hobbs battings - their organic cotton, their wool, or Quilters Dream cotton Request or their wool.
