There is a special magic with kids and cardboard boxes. A big, big love.
Okay first a disclaimer, I had nothing to do with this particular project. Emmett and Oliver found this box in the basement, got very excited about decorating it and then told me it was a costume. Now mind you, I did suggest several times that it looked a bit SMALL for wearing but they were unimpressed by my suggestion and carried on faithfully with their mission.
