I guess I hadn’t really considered just building tall cabinets instead of hanging things, that’s probably the simplest of all. I have dust collection taken care of, but ventilation is on my list. There’s a door and two (terrible) windows, so I can make it happen, but it’s not there yet. I am also thinking of adding a vent to the ductwork that runs through the room, but without insulation, that seems like it might do more harm than good.
Honestly, if you have the little pins or something similar to set them on, I’d just do all sides at once and be done with it. Set it bottom side down on the pins and then it doesn’t matter if there are tiny little defects.
