The wood ceiling in the great room and master bedroom is 1×6 clear mixed-grain hemlock. I had it prefinished, so the finish carpenters just pin nailed it in place, filled the nail holes. It’s then done. No one has to get up there again. This material is not cheap: $1.72/linear foot for the material and $0.67/linear foot for clear finish. So, this comes out to about $5.50/sq-ft of finished ceiling for material, including about 10% waste. My finish carpenter, Eric Epps, first stapled up black landscape fabric (cheap). I had him leave a 3/8″ gap between boards. This gives a nice linear effect. Everyone loves this ceiling.
