Flirty Pillows A yard of fabric is all it takes to make pillows as large as 30 X 30 inches. Cut a front and back piece of fabric to the desired pillow size, adding 1 inch to the length and width for the seam allowance. Place the fabric right sides together and pin, leaving an opening for stuffing or pillow form. Sew around the pinned fabric. Reach into the open seam and turn the fabric right side out: press. Insert stuffing or pillow. Hand-stitch opening closed.
