Yes QuiltE, the graph paper was going to be my next step. I was hoping someone else had already tried this and could tell me if it really worked. Block A is not a problem. In fact, it went together very easily and I don't think I will have any problem drafting it in a smaller size. But Block B's directions were so bad (using the Quilt Magazine Apr/Ma 2012 plus downloaded corrections) that I finally just followed the pictures. It has more 'wall tops' too.
Okay, that will be my challenge for this afternoon--graph Block B as a 16 inch block.
