3. The back of the pillow consists of two overlapping pieces of fabric that will keep the pillow form securely inside without zippers or buttons. To make the back of the pillow, cut two rectangles of cloth that are the same width as your pieced front but are each about five inches longer than half the length of the pillow front. Hem the two edges that will overlap. With right sides together, pin the two back rectangles onto the front of the pillow cover as shown. Sew around all four sides of the pillow cover.
