I ♥ Sharpie. You can just about draw on anything with them.
To break the monotony of the daily task of packing and shipping, I sometimes start doodling on the lids of our shipping boxes. I love how the black lines look on the clean matte white surface of our boxes.
One of my doodles … Art Deco inspired.
