The part of Grand Avenue known as the Design District pulls out all the stops this weekend for the third annual Design Harvest, co-sponsored by Chicago Home + Garden. Local furniture and home accessory designers, vintage and antique collectors, and local stores gather under a tent for what is basically a pop-up shop on steroids. You’ll find State Street Salvage, Urban Remains, Buckingham Interiors, Salvage One, and tons more. The free event, which is co-produced by the West Town Chamber of Commerce and Post27, keeps getting more and more popular (the first year had 2,000 people visit it and last year that number was 20,000). And it isn’t just shopping, although that is definitely the draw for me. There will also be fall activities such as hayrides and pumpkin painting, autumnal beverages including Blue Moon Harvest Pumpkin Ale and Crispin Cider, and live music. Check it out Saturday or Sunday from 11 a.m. to 8 p.m. on Grand Avenue between Damen and Wood.
