I don't suppose anyone that reads this has ever seen a tutorial for painting leather? Work in progress demands it and as I've never done it before I could use all the help I can get.
EDIT: Thanks for the attempts at answering but I think everyone might be looking for an answer to the wrong question.
I worded this poorly. I'm not trying to apply actual paint actual leather. I'm trying to color a picture of a character wearing leather in photoshop.
