The earlier post made me think that I should recommend my calligrapher. She was great to work with and she does beautiful work! The only thing is that she is in Lexington but I have friends down there so I took my envelopes down there and then had dinner with them. I am pretty sure though she will ship them if you didn't want to drive down.
I paid 75 cents an envelope and 25 cents for the inner envelope.
her name is angela and here is her website. http://www.blinkcalligraphy.com/
