Want yet another opinion? I make 3 layers of flannel, all the same size - sometimes I mix in corduroy for top or bottom - and then sew together without batting (the center layer of flannel takes its place). You don't have to quilt X's through the squares, you don't have to be sure the batting is just in the center and not coming out to the edges. Also you get 3 layers to rag, which gives more fluff for the ragging.
