I have all my old cards (maybe two hundred or so) in a couple of old boxes that Vista Print shipped business cards in. Don't really know what to do with 'em, but have always been inspired by the various stories of prom dresses, etc. made out of old credit cards. http://blog.creditcardcompare.com.au...edit-cards.php

Imagine wearing a jacket made from old airline credit cards to a FlyerTalk meetup! @:-)

Or, might frame 'em and put the display on the wall to point to when explaining how getting credit cards helps you get more and more credit cards (and miles).
