My friend gave it to me, I dont know where she got it. Its just 7X7 squares of the main fabric and you make strip sets out of 2 inch 1 1/2 inch and 2 inch. Cut them at 7 inches for the bottom and 11 inches for the sides. Alternate the rows so they dont line up. No left side strips on every other row but one on the right end. Just look at my picture and you will see it. You get 3 11 inch and 1 7 inch from a strip set or 6 7 inch cuts from a strip set.
