I don’t do calligraphy for clients as I’m busy illustrating for them all the time, but I found a great link for someone who does — Irene, at Calligraphy, by Hand. Fellow Graphic Designer Irene turned to custom calligraphy years 30 years ago. Custom calligraphy is perfect for special occasions where you’d like to set a special tone. Check her out here. Once you order your Oliner Graphics invites you could go here and finish them up! She works nationally and internationally. :D
