Covering your tables with plastic table clothes and using parchment paper on trays will also make cleanup a lot easier.
Keeping pastry cloth and rolling pin cover lightly floured will make rolling dough out a lot easier.
When baking put the first pan in the lower shelf of your oven. Bake half of the time then turn pan and place on top shelf of oven. Place another pan on the lower shelf. Continue rotating pans through the oven this way. The lower shelf helps brown the bottom of the cookies and the top shelf helps brown the top of the cookies. Don’t rely on the suggested times for baking, you will need to watch to make sure everything is baking properly.
Make sure the Christmas tree is lit and music is playing.
Enjoy the party!
