Wednesday on AT:The Nursery, they featured Moo Cards, which are fully customizable MiniCards and NoteCards. Moo Cards are able to be shipped globally, and utilize any picture you can legally get your hands on.
These seem like a great option for making personal "business" cards or a personalized gift, because you can easily do a variety--and creates another outlet to show off your pics.
Have you Moo'd? Let us know about the experience in the comments.
