The mystery BOM I was talking about had a block that had 81 pieces to it. I was able to do the blocks up to that month, then had to quit. It was way over my head. I am not that advanced. They were 12 1/2" blocks and I know me and I know it would have ended up being smaller than 12 1/2" by the time I got done with it, if I could have even figured it out.
