I'm now selling gallery-quality prints via Society 6, as well as original painted and inked illustrations via Etsy! Offering prints through S6 is looking particularly exciting, since they use far better equipment and inks than what I can muster at home with my dinky little consumer-quality printer. Their ability to print at sizes larger than 8.5"x11" is mighty fine, as well. On a related note, if there are any works that aren't currently posted to either S6 or Etsy that you'd like to get your hands on, then please let me know. Thanks!
