Most of my creative inmates prefer to quilt from the back of their quilts. The reason is because we usually use a solid fabric for backings, so they have an easier time marking & seeing the designs on the solid. It took me a while to accept it as it was so unusual. Now I almost expect to see it. These guys think so differently from the way we do that their quilting designs are wonderful when they let their imaginations take over. I have one Native American quilter who just does marvelous quilting & designs. He is always surprising me. There is one cell block where one inmate comes up with a unique design & all the others copy it! :-) I don't mind as the designs are good!
Whatever is your preference is the way you should quilt YOUR quilt! There are no quilt police!!! Go for it.
