Pen sketching while listening to Radio Theatre: The Lion, the Witch and the Wardrobe during rest hour Pen is both a joy to work with, and frustrating, as one can't erase. Since my 2nd/3rd grade teacher insisted everything be done in pen (including math), a lot of my doodles have been in pen - though I would never had dared to doodle on work for her - perhaps not even scratch work.
