Curling Cards
I pulled an old box of cards from the late 80's out of the back of the closet and put a bunch of them in sleeves with the intent of posting them on several different auction sites. To my surprise I got up this morning to find them humped up in the center with the edges curling quite noticeably.. I sat a weight on them but after several hours they are still noticeably curled.. Are these cards salvageable or what.. Might a humidifier help them out???
