Send out these invitations to your host so she can invite people and get them into the spirit. You need to create some sort of PartyLite cash (you could use Monopoly money or casino chips). Hand out the money throughout the party and hold the auction at the end.
"You have been invited to an exciting kind of PartyLite get-together. At the end of the show, we will be playing a game called “The Auction” and you will have the opportunity to earn auction money to use during bidding on surprise gifts!"
