Dry Erase Board:I took a matted 11 x 13 picture frame we already had and decorated the mat with pages from a mid-nineties comic book (Superman is known as "Man!" around here). Then I put a piece of cool-looking scrapbook paper with daily check lists where the picture would go.
Then I put the glass back in the frame, because apparently, glass is already a surface you can use dry erase on. I already had a dry erase marker kicking around.
