Just found a neat event that is held the first Tuesday of each month at the Museum of Contemporary Art. "Doodleganza" is basically a free event where people can come and experience some hands on art while they feature different artist to guide the participants into making it. It's not quite an art class,but more of an "art party" that does not require any expertise of art whatsoever.
This event occurs the first Tuesday of every month and starts at 6pm. A great "happy hour" event where you can relieve some of that stress from work. It can be very therapeutic if I say so myself.
Check out different free events every Tuesday by checking out MCA's site.
