set up your area
If you can, set the table ahead of time. If you use your everyday table for the holiday dinner, at least prep all of your settings. Take out the plates and silverware you'll need, any platters, and serving spoons.
Set up an area for guests to leave their coats and purses. Leave extra room and serving utensils for any dishes your guests might bring along.
Remember, anything you can accomplish ahead of time will make the actual holiday easier.
