It's Thanksgiving week! You've got 3 more days to prepare so make them count.
Plan seating, oven schedule, and serving dishes. Hopefully by now you know who will be joining you for the feast. Take some time to plan out the seating arrangement and what dishes and table linens you'll need. If you need to bring in extra tables and chairs, get them out and wipe them down if needed. Also look at your menu and make a schedule of what dishes need to use the oven, for how long, and at what temperature. You can even put the empty bakeware in the cold oven to see what will fit together. While you've got those dishes out, determine what food will go in what dish and write the name on a post it note inside the dish.
Clean the house. Don't put this off until the last minute. There will be plenty more to do in the coming days so having this off your checklist will make the rest of the week much easier.
