This is a classy solution for those cards that require too much type to fit on a normal card. The important thing is to have the final folded card at the standard 2"x3.5" so it will fit in a standard business card holder or file. Even with Blackberrys, iPhones, and the like being the new business norm, cards are still regularly filed. You do not want the card tossed becaise it will not fit into a standard sized card holder.
