In this video, I show you step by step how to create a Face Book Event. You will use this Event to create your Party.
I suggest setting the "Privacy" to "Friends of Friends". When it is set to this, the friends of the friends that accept the invitation will also see the jewelry. This will hopefully add to more attendees and more sales. Or you can set it to "Public". Just note that the more people that see your party, the more you will sell!
