3. Trim each printed quadrant, leaving a quarter-inch border around all four sides.
4. Leaving the paper backing on the fabric sheets will make it easier to cut and line up the fabric for sewing. Sew the top two quadrants together, carefully lining up the edges. Use a seam allowance that is just a hair wider than a quarter inch to make sure you are sewing right along the edge of the pictures and not on the white border. Repeat with bottom two quadrants.
5. Sew the top two quadrants to the bottom two quadrants to complete the square, and then peel off the paper backing from the fabric. Press seam allowances open.
6. Cut two rectangles of fabric for pillow back, each 14-by-9 inches. Fold over one of the long edges on each piece by 1/4 inch and then again by 1/2 inch to enclose the raw edge; sew along the long edge.
7. Lay the backing pieces flat, with the wrong side of the fabric facing down and the pieces overlapped to make a 14-inch square. Lay the pillow top over the backing, right side down, and pin around the edges.
8. Sew around the entire pillow with a quarter-inch seam. Turn right side out and insert pillow form.
