We love drawing with sidewalk chalk, from drawing on the chalkboard to drawing on the pavers (and constantly reminding them not to draw on the table, chairs, slide....). I decided to tape some large dark colored construction paper to the sliding glass doors and let them draw on the paper. WOW! What a hit! They loved this. I love the way they talk through their designs. Wild One will break into his new language that apparently only he and Little Miss understand (at least I think she does, because he cracks her up).
