PauletteParis. The great thing about having them for sale there is that you can customize them to fit your business, you can have the design front and back, and you get a beautiful choice of papers, and professional design. They even have the sparkling Stardream paper stock that you can choose or one that is called "Indestructible". Nice when you think that you want your recipient to remember you and your business, and not have your pretty card end up in the dreaded "circular file". Plus they have a great selection of fonts to make your name or logo look super !
I am always available to custom design business/and/or/calling cards for you so if you are interested please contact me personally at email@example.com, whether you want them printed at Zazzle or you want me to print larger cards or custom shapes for you.
