I have done a lot of that! Somehow I just need to see what happens. And it is much better than making papercuts. My wife came home once, quite a while ago, and I had somehow fallen into a trance doing papercut, literally hundreds of beautiful papercuts all over the floor. And we looked at each other - thinking the same thing... has he become a pufter overnight?

Much better just doing a bit of mirror drawing on my wacom!
