Next time you leave coffee rings on the table at your favourite cafe, get your pen out and turn it into a motorcycle. Californian artist and illustrator Carter Asmann has done just that with these great images of coffee-ring motorcycles which he shares on his Instagram account. Most of his drawings are of motorcycles because of the exposed wheels, but he has also drawn cars. We’ll forgive him his indiscretion! We especially love his coffee-ring drawing of a Honda CX500 like our MBW project bike, so we have placed it at the top of the page. Which is your favourite coffee-ring drawing form those below? How about having a go yourself and sending your samples?
