I have tried almost everything. My preference is Thermore by Hobbs because of the way it handles, drapes and feels. for one quilt for myself, I used 2 layers of it, since I get cold really easily. My second choice is Matilda's Own, an Aussie wool bat that is thick and lovely, but not cheap or easy to get. If I were doing hand quilting, it would probably be my top preference. My guild uses either Warm and Natural or Hobb's 80/20 for our LA.
