If you are looking to improve your art skills than every Friday October 5 - November 20 from 4-6PM in South End is the place to be. You (or your teen artist) will discover new techniques and even create work with professional artists. These workshops are free but do have a required pre-registration.
"The BCA and USES have come together to engage youth with workshops that foster an appreciation for the arts and that serve as a national model of successful neighborhood engagement."
The workshops will cover figure drawing, collages, printmaking, and sculpture. After the workshop the teens will visit local galleries and art studios in the area. Sounds pretty awesome to me, and no money out of your pocket!
