Kraft Paper - The easiest tablecloth you can imagine. It also eliminates the need for place cards - just write on it with a Sharpie. And when clean up comes, just roll it up.
If you don’t have at least two crockpots going on Thanksgiving, you need to work on your delegation skills.
If you live somewhere with pine cones, go outside and gather some up. Throw them around and instant decor for free.
Mini chalkboards are the best for labeling what every dish is. We have at least two food allergies happening at every function, so list if its gluten free, dairy free, peanut free etc on there to look like you really have your act together.
Another cleanup miracle - plastic cutlery.
Twine - tie it around anything to look more organic/fall themed - mason jars, napkins (add a spring of some green to be a real Martha Stewart), silverware, etc.
If you have one of those families that requires real dishes, buy some that are microwave + dishwasher safe.
If it’s your first time cooking a bird, you’re gonna want a thermometer. And when Thanksgiving is over you can use it to make candy come Christmas!
Send people home with food. Less for you to store, and they will love you when they wake up from their food coma and want a turkey sandwich.
If in all the prepartion madness you realize that you didn’t clean your house, light a candle and clear off all the countertops. It will looks and smell like new. Just keep that closet where you stuffed everything closed.
