My 12-member guild did a log cabin block challenge, red center with black and white fabrics. I won the blocks. No two were the same size. There were no newcomers in the group so you'd think we'd all come out right. I couldn't put them together in any traditional way so I appliqued them randomly to a cheery red fabric and it looks really good. You don't notice the difference in size. We recently did a garden maze block, much more complicated, and I can't wait to see the results. That block has a lot of matching points so the winner has her work cut out for her (bad pun, I know).
