Pencil & coloured pencil
If I have a pen or pencil in hand and a scrap of paper nearby, I can't seem to help doodling and drawing. I am quite sure I like colouring more than my kids do, but one of them is showing signs of wanting to pull out colouring books nearly as often as I'd like to, so there's hope. It's been a while since I have done any serious work with pencil or coloured pencil, but here are several pieces from a few years ago.
