I agree with ckcowl - I love the double sided flannel. While I never wash my quilting fabric before I use it, I always wash my flannel in hot water and dry it on high before I use it (I have had very expensive flannel shrink up to 2.5" in width when washed). I use Warm and Natural for all my quilts - I want them to be cuddly. If I were making a baby quilt for someone who lived in a really warm climate I might use a light weight poly. The only time I do not use batting is on table runners and placemats and then I have used an extra layer of flannel to give it some body.
