This week, you really don't have that much to do. Just some maintenance. Simply keep up the house by doing a quick pickup. If you'd like, make another list of foods you'd like to serve at gatherings or on Christmas morning. Look for sales and do a little shopping.
The biggest thing you should do this week is your Christmas cards. (If you send them, personally, I don't. I will see most of my family and friends sometime in the next month and I will hand them their card.) A few good online places to order cards are : Shutterfly, Hallmark and Snapfish.
