I have a drab family room that I'd like to freshen up by applying a wall covering to the back wall of our built-in oak cabinets. The family room is open to our dining room and kitchen and we have a lot of oak going on. It would be nice to bring in a fresh wall covering behind the shelves to lighten up the cabinets. We'd love to find something fresh and contemporary, maybe geometric or botanical. But not too bold or modern. We'd like to take color cues from our avocado dining chairs or chamois colored couch and loveseat. We'll be repainting and doing new window treatments, so don't have to coordinate with existing. But the picture will stay. I know that wallpaper has moved beyond the grandma styles of the past, but I don't know where to look. Ideas? Thanks!
