In the article associated with this layout in the latest addition of MR, there is an incerpt dsecribing his valance. How does Bill attach the 1 X 4s and plywood base he used for his light fixtures to his drop ceiling?
I just read through the sidebar about the lights and I can’t find any mention of how he attached the 1x4s and plywood either. Maybe a communication with the editor via customer service can get you the answer.
