When you get your blocks if you have a piece of flannel you can throw over a door you could put the blocks on the flannel for a design wall and then I like to take a picture of things that I am not sure if the design will work or not. But you can just stand back and look at it on the door. Then you can move things around and audition(put on or take off) differant colors til it looks right to you. If you take a picture it is easier to have a differant perspective on things. If you don't have flannel you can throw a plain white sheet over the door and use pins to hold the blocks in place while you decide. It would give you a differant way to look at it.
