I've always used Warm & Natural - mainly easy to get at JoAnn's and the ability to use my 40% coupon on it. However, I'm making a quilt for someone that has a flannel backing on and wanted the batting to be lighter weight than the warm & natural. The lady at the quilt store suggested the Quilter Dream Cotton. And WOW!!!! my needle slides thru like cutting butter w/ a hot knife!!!
I have one more quilt to make w/ the warm & natural and will probably be a dream cotton convert...
