The Lillstreet Art Center is offering free workshops Saturday as part of this weekend’s ArtWalk Ravenswood. Children’s activities will be ongoing from noon to 5 PM. For adults, there will be a one-hour drawing workshop at 1:30 PM and two 45-minute pottery wheel workshops at 3 and 4 PM.

Among the 150 artists featured in the annual event is Ed Zotti, long-time editor of the Straight Dope and author of the The Barn House: Confessions of an Urban Rehabber, which was recently excerpted in the Reader. Zotti will lead a discussion of his book at Waechter Architects (4712 N. Ravenswood) on Sunday at 1 PM.
