My least favorite quilt as far as how it feels and drapes was done using a 80/20 blended batting as it is what the quilt store I took it to for quilting used. Unfortunately, I don't remember if it was Hobbs or Pellon.
As I get older, I've become so allergic to wool I can't use it; even with a layer between, it makes me itch. I've had to get rid of all wool clothing, too.
The Warm Company has a product out right now, Warm and Plush, that is 50% more cotton and is needled rather than using a scrim. Quilting has to be a bit closer (no more than 6" apart, rather than 10" that W&N allows). It's available packaged for a queen size at about $29.
Alternatively, you can also use two layers of W & N. Or two layers of quilts, which we often do here near the Canadian border.
