I stumbled upon this cute idea a while ago and have wanted to make it ever since. Robert's was sold out of the squares, so I decided to just do the rectangles instead. Sorry for the horrible pictures. I think the game turned out well. I do need to spray it with some acrylic sealer because the pieces are still a little sticky from the Mod Podge.
Also, if you don't want to go out and buy chipboard pieces, you could use cut up cereal boxes instead. Same cute result, but a little cheaper!
