I've always been a huge fan of doodling (who isn't?) and I love my sketchbook for just scribbling whatever comes into my head. I'm trying out some doodle mugs with blank mugs and Sharpies so we'll see how it goes. Hopefully this mug will be crawling with amoebas!
I also found some bits in Clas Ohlson with my doodles on them which was quite exciting! I have a licensing agent and often forget that my designs will legitimately pop up over the place! :D
