Leather Saddles for Battle Cat

[Mark-of-Zee]

I have looked on the internet for painting leather onto plastic, I can't find much, maybe I am using the wrong search terms?
Anyway I am just wanting to paint the Saddles on the Masters of the Universe Battle Cat too look like leather.
Has anyone done leather on here before?

It would probably be a good idea to search for painting tutorials in wargaming forums. I know there are mounts in the Warhammer miniature games, so it is likely you'll find painting guides for leather-like objects there..
