sash

I almost always use warm and natural batting, but purchased warm and white batting for a particular quilt that has lots of white in it. It seems to be thinner than w/n; looked up product information and says it is the same oz. weight, but the white may seem less "lofty" because of the bleaching process. I really don't want this quilt to be so thin; have any of you that has used the white noticed a difference and does it fluff up a little more after being washed and dried? Thanks for your responses.
