Need Teen Sleepover Birthday Party Games

Hey i played this game at my 12th sleepover party and it also works because they count as favors too:

First you go out and buy jewelery, makeup, or any other little things for each person at your party. Then you wrap each of them in wrapping paper a few times so that they have about 3-5 layers of wrapping paper on them. Then have everyone sit in a circle and play some music while passing the wrapped item around. When the music stops, the person with the item unwraps a layer. Keep going around until the person wraps the last layer-that person gets that item. Do this game until every person has something. This can also count as part of the favors!

Ps. Hope i helped you! and ask if you need any more ideas!
