This is actually kind of cool. I ordered some new cards from a printing company called MOO. They let you upload as many images as you'd like (well up to 100) and then they'll print them as business cards
I chose to have the reverse side remain fairly plain and concise
I was really happy with how they came out and can't wait to start giving some of them out. Do you see any images from your shoot on the cards? Let me know if you want one/some. This seems to be a product that would appeal more to photographers than anyone else, but I thought I'd share.
