I had some free time and made some sketches of labels that you can use to stick on the SD cards and made some that fit those plastic SD card holders
What do you think of them? If you like them, I might release them here. I made SD stickers for Debian, OpenELEC and Arch, while I was a bit more optimistic at the box labels and made a quick MeeGo and Android sketch as well.
What else would you like to see?
