Horse Cards??

I am looking into making my own cards. How would you feel about having personalized cards/invitations?? Possibly featuring yours, or a friends horse? Maybe just somthing cute or fun w/ horses on it? Maybe just make blanks that people can order to say something they'd like in it....
Any thoughts?

Nice idea, I'm sure people would love them. :)

What would attract people to your business, when they can do the same thing at a trusted company like Zazzle or Cafepress?

I have no idea what those are... But really, that's why I'm asking.
I have a friend who makes cards from Stampin up (C) stamps and paper and sells them on ebay.. but they're not really personalized.... I just wondered how they'd do. But thanks.
