A simple thing like reminding oneself to defrost a meal, quickly turns into a messy doodle.
When I'm working in the computer, I always have a piece of scrap paper for random notes and phone messages... but most of the time, they'll be completely filled with small drawings in a matter of minutes. There is something about not doing what you are suppose to be doing.
Going through my desk drawer, I came across this colorpencil drawing. It was made a late night before christmas. My wife and I were writing the last batch of christmas greetings, and I was a bit frustrated about not getting started early enough to do all home-made cards ( maybe this year ). We were gluing pictures of our son on colored paper, and among the stack of unused pieces, I found this sheet, perfect for a little drawing. (that's true for all surfaces where you can leave a mark)
