I had the idea to be Jack from “Jack in the Box” for Halloween. The head was a plastic dome from a Halloween fortune teller globe decoration and I wrapped it in a stretchy white see-through cloth that I glued down. I cut the mouth, eyes, and hat out of colored foam sheet from the craft store and the nose is a Styrofoam cone that is wrapped in a black cloth.
To wear the head I hot glued an old bicycle helmet inside so that I could put it on and strap it to my head. I won my high school costume contest and I wore the costume into my local Jack in the Box and had parents taking pictures of me with their children.
