Erin and Nicole, graphic designers and girls after my own heart have an amazing little custom invitation boutique called Bird and Banner, which hopefully you have heard about from the buzz in various wedding publications and design blogs.
All of their work is delightful and well-designed, and as stated on their website, they are sensitive to formal aspects, but also hand print most of their pieces. I just love that, the best of both worlds. Be sure to check out the rest of their work here.
This card you can also pick up at their etsy shop.
