Bring a bag of candy with you to the party (Hershey Kisses, etc.).
Tell guests not to eat the candy during the game. Call a letter of the alphabet, and the first person to SHOW an item from their purse representing that letter wins a candy.
Each person who wins, gets a piece of candy; the person with the most candy at the end of the game is the winner.
Only use about 8-10 letters or so, then stop the game and do your party demonstration.
You can play the second half of the game at the end of the demonstration, but this time the guests must ask you questions about your direct selling career and company to earn a piece of candy. Imagination counts. It could be a description of an item, the brand name, color, etc.
You'll notice that the same things can be called different names, but they all work for this game. It's a lot of fun to see what people think of when you call a letter. Sure to bring you lots of laughs.
