It's the lap size, took 112 bricks and 4 patches. I followed the directions that were originally given. I thought about making it bigger, but it required more bricks than I thought I could find, without repeating any colors! :shock: The finished size is: 48.5 X 79.5, but I tend to use a "scant" quarter inch seam allowance. Please be sure to post a picture when you finish yours!! Can't wait to see them all!
