Just a quick question. I have a jumbo "packet" trick consisting of 4 cards that have been accidentally stored in some sort of weird "S" shape that they retain to this day. They're cockeyed and I was wondering about the best way to straighten them back out.
I was thinking just pressing them between two big hard-back books but I was just wondering if you guys had any other suggestions. Thanks!

You might have to get them a little wet first... But of course you take the chance of really destroying them...
Good luck..

If you have one of those steam cleaners you could try steaming them then placing them under something heavy, I have done this to papers that were bent.
