I am making a bedspread where I have sewn long columns of fabric onto the Warm and Natural batting and the backing all at the same time using a stitch and flip method.The sashing is 4" x 104" and the coins are 8" sewn into strips 104" long. Do I need to quilt in the sashing and the wide strips ? The directions say I can leave 10 inches unsewn but does that apply in both directions?
