Use black batting ( Hobbs) When I make quilt with black backgrounds and black backing. ( like my Backyard Gathering quilt- which is wool appliqué on black flannel with black cotton backing) black batting is nice to work with. I haven't tried it on a quilt with multiple colors. I did use ( Dream green) batting in a quilt with mostly light fabrics, even whites and had No show through at all. It too was nice to work with.
