When I make denum quilts I sew the backing to front, wrong sides together, turn right side out, slip stitch opening closed, then tie with embroidery floss at the intersections of the blocks. Then you don't have to mess with binding. I have made several denum quilts this way. You can match the floss with the backing. Let me know if I can help you more. If I was near you I would come help you. Hope you are using Oklahoma State Cowboy's material for the backing.
