Just been to a mates place, some excellent wall paper in his place, if it’s a small area you can afford to go up market as the cost per m won’t kill you, it will always be dearer than painting, but will add so much more with a good design.
the pic is something I’ve just done, loads will hate it, some will love it, it’s you house, no point asking other people’s opinion on this really.
happy wife, happy life.
