Framing all done. Door opening needed to be 19" high, but I forgot to compensate for the 1/2" ply I'm going to use for the internal shelf. It'll run over the top of the bottom edge and all the way to the back of the Hardibacker so the opening should be 19 1/2" high... This came to me as I was lying in bed watching TV. No big deal, I'll just need to pull the top rail and cut down the 4 cripple studs.
