I just heard about a website called HouseParty (here). You sign up and then host a themed party. You’re supplied with products for your party — all free! There are food parties, TV show parties, game parties, kids’ toy parties, and many others to choose from.
I just signed up for their e-mail notifications. They’ll drop you an email when new themes are added. So, stop by their site today and see what kind of party you can host!
