InkedFur allows furry artists to apply, and we select artists based on the quality of their most typical content. We allow most skill levels but we want to make sure their images will make for good prints.
Also bear in mind that many popular artists that have been in the fandom for a while have already established a printing solution and may not be seeking new printing options. However, we typically reach out to these artists to see if they'd like a secondary method to sell.
We at InkedFur believe you can never have too many sites to sell your work, and we never seek exclusivity. If you know an artist that does high-quality furry artwork and could benefit from our services, please direct them to http://inkedfur.com/interested-artists, where they can read what we have to offer and apply to be a creator on InkedFur.
