· Typical Ghoul Next Door
Large hula hoops? Maybe 3-4 of them. I have some from the dollar tree that are at least 3 foot rounds, but possibly 4 foot diameter... Cut and then tape together combine together with duct tape to create a stable frame, and then use cardboard strips (also attached with duct tape) to make thin support ribs and then maché over the entire structure. That's what I'd try anyway.
