Has anyone tried using Insul Bright in a quilt? First question is it breathable enough for a quilt. Seems I read somewhere that it was, but can no longer find the reference. While I realize there is not r-rating associated with it – alone it might make a pretty good summer quilt. I wonder what kind of temperature rating a quilt made of 2.5 oz XP and a layer of Insul Bright would be?
