2) Serve buffet style. A buffet makes it easier to offer multiple dishes. You can make most in advance. It's great to set up stations for main dishes, cheeses, desserts and lighter fare. I love to place dishes at varying heights and use cake stands, glass bowls and footed trays to do it. Need some recipes? Check out Cooking Light.
5) Show them where... Set aside wicker baskets or large planters for throw away and recyclable items. Make them festive and guide your guests to use them. Have trays for glassware and encourage empties to be placed there. Makes it easy for you and neat during the party.
