I'm really getting into the design now. I've placed several blocks and am at least partly pleased with the design that's developing. The little pieces of paper are marking the center of a block (otherwise I get confused), and the tissue paper is to show where the next block would be so that I can tell what color piece to try next. Working out some of these tricks has helped a lot. The hole in the right side should be green, but I'm short a piece at the moment.
