If you're just starting out these supplies can get a little expensive. Go to garage sales and thrift stores. It can save you a bundle. You will need a table or large enough counter top to hold all of the food. If you do not have one of these you can rent or borrow one.
Plastic milk crates work great.
You can cut squares of fall colored fabric to cover them. This is for all the extra drinks as you won't have room in the fridg. Plenty of silver or plastic ware, serving spoons, a carving knife and meat fork, 1ea. Plenty of napkins, plates, bowls, drinking glasses or cups. Plastic bowls with lids work great.
