I had a nice big room in my basement with lots of counter space and storage and ventalation nd stain-proof counters and a big sink and...windows. Now I could have just tacked some heavy duty plastic over my windows, but it's hard to drill into brick. So I cut some ply-wood to the size of the windows, wedged the in, and went around the seams with a few layers of black duct tape. It looks funny, but I can print in the day now, so whatever.
