I've recently created a shop on Etsy called Print Pantha. It's early days yet but I'm slowly and steadily, whenever I get the time inbetween my book cover designing, etc, adding new artwork for sale. There are only a few printable items in the Etsy shop at the moment but it would be lovely for you to follow me on there and you can be the first to know about new items as they're uploaded. The plan is also to sell framed prints - watch this space.
