How do you label your micro sd cards?
I use micro sd cards for audiobooks on my Sansa clip+s. I bought this sd card holder in order to organize them and know which books are on which cards. By labelling the card slot and making a list of books that go with each slot, I figured I'd be able to keep track of where to find a particular book. But the darn things just slip out of the sd card holder slots. How should I label the cards themselves so that I can keep track of what's on each one?
