Little and fun and exciting, I just got my MiniCards in the mail from MOO.com. They're about the same length as regular business cards but only half the width. You can use provided images or your own photography on the cards. 100 cards come in a pack and each card can have a different image on the back.
I used ten of my own photos and then on the reverse I listed my company, blog site and email address. Simple, fun and so exciting!
