I like thid spread/layout...costco....a backyard wedding: cheese, crackers, grapes, nuts and olives spread. Alot of people suggested for inexpensive appetizers to go to costco and get various snacks, like crackers & cheese, or a few bowls of various nuts. Things to snack on, not too heavy and not too much.
Container House - get or make some cracker / biscuit / cookie boxes and play with them. Think outside the container, use open spaces that you could SIPs, or metal stud or other sustainable materials. Don't forget to think of solar, water and wind.
