In case you weren’t aware of what online publishing options are available to you outside of Amazon’s self publishing and Etsy, I’d like to bring your attention to another market: DriveThru*. You can read about them here. In general, their cut is roughly 30% of your sale over any printing costs. I have enjoyed looking over the material they have; at the very least it could be a way to get out some of your work and into the hands of others.
Who knows? Perhaps some of Redemption Studio’s work may end up there soon.
