Hey,
I will be moving into a house that has a 15' x 23' garage that my wife, so graciously, said I could turn into my shop. I am thinking about doing a wall full of french cleats. The garage is finished (drywalled). Would you all recommend putting plywood up over the drywall before putting the cleats up or attaching the cleats directly to the drywall? Also, would there be advantages to using 1x lumber vs plywood? I have access to a lot of rough cut white pine, poplar, and white oak that would be the same price as a 3/4" 4x8 sheet of plywood that I could use for the strips.
