The contemporary coffee shop is one of the best inventions of the 21st century, don’t you think? Dozens of people sipping lattes while working on their laptops, reading and chatting. This week’s sketch is of a guy sitting at the table next to me. His shirt wasn’t actually orange, and there were no paintings on the wall, but hey, this is sketching, not photography. Do you notice the “lost edge” on his face? Lost edges allow us to use our imagination to fill in the rest.
