toddler art project

We were lucky enough to have a large piece of corrugated cardboard in a box we have. it is maybe 1 yard square. well it it the perfect surface for coloring. I just lay it on the floor and give my son some crayons. he sits on it or lays and colors. The crayons make a cool sound running over the ridges in the cardboard and it seems to hold his attention a little more the regular coloring does. It's so large that he's been able to color on it several times and we're not done yet. This has definitely been the most coloring I've been able to get out of my kid. Maybe yours would think this is fun too.
