I've used flanel a few times as batting on baby quilt because it makes such a supple, soft, wrapable quilt that easily "molds" around every little baby part like a glove.
Wondering if flanel would be a good alternative to use in the cotton theory quilts. I'm not familiar with the method as after fingering one of them I did not like the stiffness of the quilt - Jacquie is right on the money. It definately reminded me of the braided rugs!!
