My cards currently say TAROT up at the top, over a picture of one of my own deck's cards. (usually Empress...or Moon)
Then DIVINATION AND CONSULTATION
My name
Phone number and e-mail.
I used to have much more written on the card...about the types of readings I did...but this one seems to work a lot better. Simple and to the point.
(plus I can show off my artwork on it...in case I am out of my other business cards!)
I don't have a cell phone, or I would have put that number instead of home phone.
