Its definitely all about the playing, and watching Tims videos. One tip- DON'T throw any of your play pieces away! Even if you think they look terrible. What I do is stamp an image onto a piece of acetate (I actually use OHP film from Staples) then lay it over your inked pieces.You can move it around, change the orientation, etc. You will be surprised how often a piece will come to life with the right image on it, even when you were ready to bin it.
