There was paneling on the walls of the library. Choice–take out the entire wall to hang new drywall, or just put the drywall on the bottom and–my idea–install a chair rail to separate the two different materials. I think it worked!
By the way, we won’t discuss my skepticism about how this happened while the painters were painting the trim work.
But as you can see from the first photo, Contractor Keith fixed it. He didn’t see my meltdown, but he heard about it.
Work and photos pictured here actually occurred later than post is dated.
