I have a backround wall (do you call it that?) in my bedroom. Which basically is a wall that is different from all the others. My room is red except for the wall by my window which contains a wallpaper (seen on the pictures) it’s hugely popular in Sweden. And I love it because you don’t have to commit to a certain wallpaper and you don’t have have a singular colour in your room and then have to decorate the walls to make it more interesting. It’s basically a wall decoration on the entire wall.
I love it, my room as a “theme” which is cities. My wallpaper contains cities and I have two huge paintings/picture of New York and London.
P.S. My bedset match my lamp
