This costume idea originated in a school project. We were challenged to design a marine related costume using only slotted construction and recycled cardboard. We were not allowed to use any type of adhesive that could prevent the ability for the costume to separate and store easily. As the project progressed, new ideas were formed, and eventually, the final product came to be.
In order to promote the "being green" concept, build a costume using recycled cardboard. Use slotted construction and no fasteners or adhesives to give the costume the ability to store flat and easy.
- use recycled cardboard to build costume
