Perhaps the ultimate way to create a stress-free holiday is to live by a list. Plan ahead, and don't be afraid to delegate. "Know what you're capable and comfortable doing and give other people things to do," says Kathy Gunst, culinary expert and author of Relax, Company's Coming! and co-author of Stonewall Kitchen Harvest. Asking guests to help with a party-related task makes them feel more involved, so never be afraid to ask.
