The Medford Public Library invites teens in grades 6 and up to learn how to write and draw your own comic book. Each of the four sessions in this workshop series will include a guided lesson/activity and independent work time, ending in a mini-comic book created by each teen. No sign-up is required! Teens are welcome to attend one or all sessions. Dates are April 17 and 24 and May 1 and 8, from 6:30 to 7:30 p.m.
