I have certainly noticed bare walls more and more lately.
I like the naturalness of it, the raw and honest feeling.
Honestly, one method is to strip the wallpaper and see what you find underneath. With a little polishing, this wall has great potential!
Or you can have your painter / finisher apply various paints or textures and see what you come up with.
Mix several colors of lime paint and apply.
Of course, the masters are John Saldino...
and Axel Vervoordt. These walls speak to me!
Have you incorporated bare walls into your decor? I would love to hear about them.
