I've had these blocks around for months. I have more of the 16 patches, about 10, but this is all the X blocks I have. Its made from 3 1/2 in. unfinished squares, and it already fills my design board. I guess I was thinking I'd make a queen size when I started. Also I miscalculated and cut about 100 more blue squares than I'd need for even a king size. There will very likely be more quilts with these squares! I used 53 different fabrics in all the blocks I have. I'd love to get this finished but am intimidated by the size.
