Look carefully at the picture, though. The hst are always going in the same direction or even put together the same way. I'd label the different ways some of the blocks are sewn together (block A, block B, and so on) then figure out how many of each you need. Every time I tried, I got confused, so you might want to print a picture that you can write on. That would have helped me. Let us know if you figure it out.
