I have a large living room that at the very end has a wall that starts out low on the left side then ends up high towards the right side. In the middle of the wall I have a sofa - sofa table in front of that - above the sofa a large mirror, On left of sofa an end table with a table lamp - on right it is bare but still have room to put something there because the ceiling is so high and it looks empty, What could I do ???
