|I've usually been marking the backs with a bee or some other sort of 'b.' Recently, I've started adding things more in line with the eventual sender of the cards instead. That is, IF anyone would send the damn things. Stop hoarding, people! Maybe I should give a card to everyone else and have them write to the recipient. Wait, that's not such a bad idea...|
The rivets are another new development. Though, I'm not sure if I like them. I find that they tend to bung up the paper a bit wherever the back of the rivet touches the card.
