One heck of a cardboard box
Making environmentally friendly toys has become a priority for a lot of toymakers, but one is taking that to a whole new level. Cardboard Design has come out with a line of sturdy, foldable cardboard play environments that are beautifully done and incredibly kind to the planet. My favorite is probably the Lemonade stand, coming later this year, but even the Rocket Ship and the basic playhouse are wonderful. They can be used au natural, or painted, crayoned, stenciled or collaged into a work of art. The cardboard is very thick, and with reasonable care should last a long time.
