HandyMan and I made up some business cards in preparation for our upcoming event. Have you heard of Moo cards? I think they're the cutest things. You can upload your own pics or use some of their stock designs like I did with this batch. The pics or designs go on the front and six lines of text go on the back.
There's so many things you can do with your Moos. We even used some as favour tags for our wedding. If I was an interior designer, I'd put different pics of rooms I'd done on them. Some Moos are so coveted they get traded... like baseball cards... but without the stick of bubblegum ;)
