Kat Sloma again hosted the Liberate Your Art Swap this year. "The swap encourages you to create, share and liberate your art into the world where it can do it's greatest good". Kat reports that 1290 pieces of art were liberated this year.
I've been using postcards as a format for making art but hadn't taken a photo of a piece of my work and then turned it into a postcard. I used Zazzle and was really happy with the quality and turnaround time.
