I daydream about that world LOL. With my art, it's mostly digital and so will be printed out, however many times it's ordered but since I use sites to do that side of things for me, what I do is work out a per sale price what I'd like in commission, and let the site take care of the rest! I sorta like that as it takes the pressure off me to try and price things myself. I do feel tho, that my work deserves a decent return when sold for sure, I am proud of it and how else will people know I am proud of it other then the price I put on it?
