I got a request from Karen to show a pic of the back of my quilt. so here is part of it. I am happy that there is enough quilting on the back, I quilted in the ditch around all the blocks, and around the pieced triangles, plus several rows through all three layers on the scallops.
It seems adequately stable to me, nothing is shifting, and I don't see how the batting could shift, because it is well quilted on every block, and they are only 4 1/2in. I don't necessarily think that this method would work with say 12in blocks, unless you did some extra quilting through each block, but with this size, I am not worried.
Back of the corner of my quilt.
