I never grow tired of doodling. I rediscovered my Faber-Castell PITT artist pen-kit in a old bag full of drawing equipment. I didn’t like them too much before, but they have sort of grown on me. They work almost as a multiplier brush in photoshop, the more strokes on top of each other the darker the color gets.
