After many years of meaning to do it and not actually doing it, I decided to open an Etsy store. It's not my first online print store. In fact, one of the key reasons I ever learned HTML, CSS and PHP was to build an online store for my artwork back in... 2002? Seriously? Seventeen years ago...?
Anyways... I've put in a few prints so far, mostly from the Octoplural series of paintings although my current favourite is the My Day Flowchart.
I really like how I could tie Etsy together with Printful so the prints are generated on demand rather than me holding a lot of stock which is how we did it back in the olden days...
