Planning and orginization is everything. When it gets down to the wire, you want everything to flow smoothly, and you DON'T want to be so over-worked and flustered that you can't enjoy your guests.
I start way ahead planning my menu and who will bring what. Then I go through my recipes and make my shopping list.
I prepare and freeze or refrigerate anything ahead of time that I can. I also do all my chopping and dicing, and put in ziplocks in fridge.
Then I get a game-plan in mind and make notes for myself. (Since I like to drink a wee toddy while I cook, I've found that very helpful.
My mother used to set her table the day before, using all her prettiest crystal and china, but I can't do that, as I have a pair of Siamese cats who are very curious, so that job goes to my daughter just before we eat.
And I don't hesitate to ask for help from any of my guests...stirring a pot, taking up ice, watching the rolls, etc. Our kitchen/living/dining areas are all combined in one big L shaped room, making it easy to keep everyone involved.
One hint about your table setting...I have bought several sets of pretty dish towels to use for napkins. They are nice and big, and easy to wash.
Depending on how big the crowd is, sometimes I set up a separate table for the kids at our big round coffee table (cut down from an old round oak table.) They get candles and flowers like the grown ups, so they think it's pretty cool, and we get their plates fixed first, so the adults can relax and have good conversation with their meals.
