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.
Yardages are rounded up to the next 1/8 yard. * Calculations add 1/2 inch to border widths for 1/4 inch seam allowances. ** Backing margin is the number of inches that the backing extends beyond the quilt top at each edge and is necessary during longarm quilting. *** Straight grain binding.
