Check out the color blocks I made to use with Molly. I saw this idea to make you own on a blog that is no longer available. They are inspired by the Montessori Color boxes. They are so much cheaper to make a set on your own, almost free if you have stuff on hand. I used a piece of thin wood, cut and sanded. And then Mod Podged paint samples on to them. I made 2 of each color, so someday we can use it for a matching game as well. Right know, Molly loves to name the colors and stack them all up.
