What I did last year was buy those small treat bags that are like 10 for $1 or something like that. I put a piece of Smartie candy (be a Smartie, have a Party) and a couple of other small candies I got at the Dollar Store.
I then put a pen, Order Form, Catalog, and business card in each one and handed them to each guest as they came in the door.
In random bags I put in a Citrus Peeler or Twixit! clip or something small like that.
I put the bags in my WS Rectangle Server to show a different use for it.
