You can find inspiration anywhere. I was walking down the isle one day at Walmart and saw this bag and fell in love with it and immediately knew where I wanted to duplicate it.
I got this at Marshall's, it's a tic tac toe board. It suggest you put pictures in it but I wanted to use scrapbook papers, yet another opportunity to get to look at my favorite papers. If you can't find one of these I think the same thing could be done with a big picture frame. For the x & o's you could use buttons, or probably find wooden x & o's at the store. This sits on my coffee table, just adds a bit of whimsy to my room.
