How do I finish this wood box extension I made, to match the drywall around it?
I have used a wall paper that has the same surface texture as drywall in the past to cover custom jobs like this. I like the look better than just primer and painting. From my experiance there will be less cracks at the interface from the block of wood to the ceiling and the paint color is uniform where going from sheetrock to wood there is usually a shift because of the texture difference.
