I played with some keychain holes, but left them off because I think that actual keychains would be a good fundraiser for the group.
It definitely needs to be a thicker part of the card so the keychain doesn't rip through. That B might work, but I think that they'd have to go next to the QR code to really hold up.
I'm down for either option. What do you guys think? Hole or nah? In the top or the bottom?
