Hi Everyone, I have a question about pre-mixing paints with medium. Mark Carder has a nice little video on this. He pre-mixes a tube of paint with slow-dry medium. I'd like to do this myself because I think it might make painting more efficient. But what medium to use? Can I make a medium with linseed oil and natural turpentine (all that I have to hand)? Should I get some slow-dry medium? If so, what kind of slow-dry medium would you recommend? So far, I have only used Liquin Original for a medium. It has some advantages, but I don't like because it dries so fast and is rather sticky. Of course, I have properly mastered it, I'm sure. What about you guys? How are you using medium, and what medium do you prefer? No doubt we will all try the Geneva paints sometime!
