Wrap a small gift in a small box. Put the box in a slightly larger box and wrap it. Then put that in a slightly larger box and wrap it, and so on. Keep it going so you have as many gifts as you need or want. Write a message on top of each box such as - This gift goes to the person standing closest to the tree. That person gets the gift, opens it and finds the next box with a message that could say something like this: Sorry! This present goes to the person who is sitting next to you on the left! That person then gets the gift and opens it. The next message can say -This gift is for the person whose birthday is closest to December 25th. The last message can say - This gift is for the person who washed the dishes. Use your own ideas to decide who will get a gifts. You could have several of these gifts going at the same time to add to the fun of the party.
