i say combine the person who posted to make the blocks wonky with shopella's suggestion. make the block crooked and then do a yellow brick road around the blocks ( so they will be a nice square) and for a boarder to finish it off, use the red in the block to tie it in. and for the reverse use a very colorful rainbow like fabric or even a fabric that has little rainbows all over it. for the quilting I would use a tornado or slippers or the dog pattern. use invisible thread to highlight Dorthy or another in each of the blocks also.
