· Macho Nacho
You finnaly have a theme.I would definitely vote papier mache, I mean, you have 229 days or something like that right? I have a Pumpkin heavy theme this year, so I am having to kick out a bunch.... right now, i have 4 going at a time, and that means it will only take me about 5 to 6 nights of putting one layer of mache on each, and letting them dry overnight, and I will have 4 pumpkins by the weekend.
Trashbag, newspaper, flour, water, glue... can't beat that for cheap, and the possibilities are endless for decorating them.
Good luck in whatever you decide, I hope its fun for you!
