Thanks for posting that article, TxAphi! I'd never read that before and it really summed up the tradition nicely!
My sister is planning a nice cookie table at her reception this summer and most of the female relatives in our extended (ie big Italian/Polish clan) family are making cookies for the event. She didn't ask me, though, since it's common knowledge that I am the world's more incompetant baker.
Notice, whenever there's a thread with the words "Pittsburgh" and "wedding" in it, it's only a matter of time before the cookie table gets mentioned!
