I participated in a similar thing years ago. It was set up like a chain mail. The letter had a list of names on it. When you received the letter, you sent your item to the next person on the list and put your name down at the bottom. Each person in turn did the same thing. This went on for ages and my name came around a few times. This particular chain was for pretty kitchen dish towels. I still have a couple of the nice ones I was sent.
