We just had our calligraphy done by njwcalligraphy on Etsy.com. Her name is Nellie Barker and she was such a joy to work with. She was super responsive, worked with us to create the perfect envelopes, and got everything done in record time for very low rates. This is my favorite vendor so far. Definitely email Nellie if you want calligraphy.
