I am planning on creating an exposed beam ceiling look in a room since my house has nice, thick, redwood joists. I was thinking of putting drywall between the joists and leaving about 2" of the 2x10 joists exposed. I would put 2x2's across each joist cavity to have something to screw the drywall to. Was also thinking that using a J bead on the drywall would give it a nice, clean edge. Any thoughts on this? Would it look decent? Am I mad for creating so much work for myself? The room I'm planning on doing this to has 14 joist cavities in the ceiling that I would have to finish.
