2) Paint it white and the top silver (I used satinwood paint)
3) With the same white paint used for the sides, paint on a road. I used the same idea as a labyrinth so that the traffic would flow from the roundabout, and used a 'business' size envelope to guage the size.
4) Find cool stickers and get the kids to decorate the sides. Mine cost E2 from a discount store. I carried on the car theme.
5) A voila, a completely transformed playful toy box, put together for a pittance.
