__Make arrangements for any items you'll need to rent or borrow.
(1 to 2 weeks ahead)
__Telephone any guests who have not responded to your invitations so you can get a definite guest count.
__Do preliminary housecleaning, especially any time-consuming tasks. Make sure all appliances that you'll be using work. If you're grilling, don't forget to buy charcoal or fill the gas canister.
__Compile your grocery-shopping list. Check on items such as matches, candles, and liquor, and add the things you'll need to your shopping list. Don't forget ice.
__Check that table linens are clean and ready to go. Decide on tableware and serving pieces. Wash infrequently used pieces. If you're using disposable paper or plastic items, inventory what you have on hand and add the items you need to your shopping list.
__Order any special flowers, meats, seafood, or other ingredients you'll need.
__If you're making decorations or centerpieces yourself, now's the time to get started.
__If possible, make some foods ahead and freeze them.

__Go over the house again for a final cleaning check. If necessary, move furniture.
__Prepare the foods according to your timetable so everything will finish when needed. (Wash dishes as you go along to save cleanup time later. Don't forget to run the dishwasher, so it'll be empty and ready for party dishes.)
