I have just finished a new 3.5″ X 5″ card to pass along to petential clients.  I like this size card because it gives a lot more room to show some of your work, and it dosn’t get lost as quickly as a business card.  It is not as informative as a brochure, but much cheaper to print and gets clients to your website. I just have them printed at the local lab as a 3.5 X 5 glossy print, and on tuesdays and wednesdays, they are only 6 cents a print.  Not bad.  Let me know what you think of it.
