You should see my log cabins - totally scrappy. No two blocks are the same. All you need for a successful log cabin is to have light on one side of the diagonal and dark on the other. I usually make 9" blocks (with 1" logs) but you can do many other sizes and numbers of blocks. (Just make sure the blocks are square so you can turn them different directions.) Judy Martin's log cabin book has lots and lots of layouts for standard log cabins. Have fun with those blocks - they will make a gorgeous quilt.
