Measure the width of your quilt and add 4-6 (or chosen excess). Design a backing to equal that width, adding 1/2 to each panel for each seam you'll use to sew it to a neighboring panel. Cut panels to the length of your quilt plus 4-6 (or chosen excess). Sew panels together with a 1/2 seam allowance. Press seams open to reduce bulk. Press backing before use.
Because my seam is 1/8 wider, I have a very nice full binding when I turn the binding to the back of the quilt to stitch down. Stop sewing 1/4 from the first corner; backstitch. Remove the needle from the quilt and cut the threads. Fold the binding up, then back down even with edge of the quilt. Begin stitching at the edge of next side, backstitch to secure and continue sewing. Repeat at all corners. Stop sewing about 6 to 8 from where the binding strip started on the first side.
