The Eleventh Doctor Costume

This is 5 yr old Colin in his Doctor Who tardis. He is wheelchair bound and I built this to fit around his chair. I try to incorporate his chair into his costume in some way every year. I cut out the walls from foam poster boards and attached velcro to the edges to easily break it down and set up. Once it was put into place I zip tied it to secure to his wheelchair in multiple places for stability.
