There is a lot of different options to avoid the typical semi-gloss on drywall look. One I recently came across which I really like is putting leather on walls. Having a finely tanned hide on your wall will be a welcome change from the typical wall. I searched for a bunch of “leather wall” pictures, and posted them here foryour consideration.
