I don’t know about you guys but I hate blank walls and am always seeking out embellishing mine. Yes I have art on a lot of them but on occasion and actually quite often I will panel them or wallpaper them for instant intrigue.
I then get instant texture. Wallpaper is personal obviously I tend to go for architectural style wallpapers, or velvets or grass cloth papers that are rich in texture and add a new level of softness to my walls. The big thing with walls is to embrace your own taste and individually. Be fearless, ignore anything any friend or family member tells you and make your home the happiest places to hang out on the planet.
