I did not use binding at all Would you beleive it??? Ok you will need two pieces of fabric. The outside piece is 6 1/2" x 5 3/4" The inside piece is 7 3/4" x 5 3/4" Now pin the two pieces together right sides together, they are not going to match as one piece will a little bit longer than the other piece. That's the way it is supposed to be, this is the magic of it. Ok sew the short ends matching the raw edges and then center the outside piece and then press it.Now turn it right sode out. Now fold in the short ends that were just sewn and pressed to the center on the inside piece. It will be the largest piece of fabric and pin. Now sew the the open ends on each side and then you can turn them right side out and you will have a nice tissue case and the magic of the larger piece will look like a binding on it.
