I made a quilt with no batting and used flannel for the backing. I will not do that again. I love the top, but wanted the quilt to be lighter weight. I thought since the back was flannel that would be enough. But I machine quilted it and the stitches do not look as good. When there is batting, the stitches are imbedded somewhat for a much better look. I think if you use poly or wool batting instead of cotton you will get a lighter quilt.
