Ok, i cheat a bit ( that fit's the playing card theme somehow *lol*), because the background of the tag is definitely paint. I had a play with a Master Skinner technique and he calls it *Walnut effect*. The tutorial can be found here. I'm always trying new techniques on smaller surfaces before i start a new project and because i'm never wasting anything, i used this tag as background, for my excuses.
Thanks so much for reading and leaving your very appreciated comments (:o)
