Found this today.

Isn't this so cool! I probably couldn't pull this off in my house because I have such different decor, but I love it! I found this on the "image is found" blog. They are a husband and wife photography team in southern california. Anyway, this is something they did in their home. These are just three white magnet boards from ikea, and mini magnets. Both very cheap. I know, I have one in Rachel's room. They can just rotate pictures this way, since they are always taking them. Wanted to pass the idea along. Inexpensive, creative, and lovely.
