what to do with those holiday cards?

What to do with all of those holiday cards when the season is over? As a stationery designer, I like to hold on to each year's haul. ALL of it- the good, the great, the bad and the ugly. It's a great way to do 'market research' and to see what else is out there. It's also serves as a reminder as to just how many cards I need to order next year (I WAY under-ordered this year...I hadn't taken into account the new friends via my son factor). I used some pretty leftover cord from present-opening, tied them all up, and slipped them into a large envelope from Paper Source and labeled them 2008. I put my own card on top, so I can keep track of our holiday cards each year as well. Do you do anything creative with your cards?
