The jellyfish cardboard costume was a result of a high school technology midterm assignment. The objective was to create a costume for halloween, a party, play, or other function for a middle school child, but made only out of cardboard. A cardboard costume,created by the user, is a less expensive way to have a great costume, and to "go green."
I plan to design and produce a marine themed costume made completely out of cardboard. I have chosen a jellyfish as my costume inspiration.
- Used by middle school children ages 10 to 13 years old
- Intended for a play, party, Halloween, or other function
- Only material is cardboard
- Slotted construction
- Flat pack design
