I've talked a lot about branding and design, and the importance(Importance of Branding post) of it. As you grow and have the resources to work with great designers your brand gets tightened up. I had my friends over at Brand Envy, http://www.brand-envy.com design these fancy letter pressed business cards for me that fits to my branding scheme. The cards are 2 colors on one side with hand painted edges on 220lb paper.
They have branding packages for different levels, so I would definitely recommend connecting with them to create a branding scheme for you. Just tell them you heard of them from me.
The actual letter pressing was done at Dolce Press.
