I am trying to put picture frame faux wainscoting in my downstairs PR on the lower half of the walls. The design is a very simple box created by attaching four wooden boards above the baseboard and then placing a chair rail above the picture frame box. The confusing part is that this room has 5 walls of different sizes, plus a recessed area behind the sink. (Please see attached drawing). All the corners are bull nose.

I don’t know if I should try and put the vertical boards of a box at each corner in the room (there are 9 corners) and create multiple different size boxes, or stay with a uniform spacing of the vertical boards for every box and cut/bend/attach the horizontal boards as needed to get around all of the corners. Will either or both look terrible? Is this room just a bad candidate for faux wainscoting?

I posted a while back about this same PR after it was professionally staged and I was unhappy with the outcome.

I've posted this in the home decorating forum and any advice would be greatly appreciated.

Thank you for your help.
