One of my jobs in college was working at this dive bar called Benny’s- it had great jazz and my coworkers turned every night into party night. I was always intrigued by the sketches people would leave on the tables explaining the mechanics of some mysterious object, or a route to an unknown locale.  I pulled a couple of my own sketches out of my sketch book to give you a before and after look at two hats for kids. Not much mystery here. The sketches- and the finished products.
