Don't hate on the hard edges. The addition of big, bold rectangles is a statement that won't go unnoticed and can be just the focal point that a living room needs to feel complete. Four very different ways to go about it and what they do for the room:
• In this room from Elle Decor, a painted triptych comprised of three vertical rectangles adds color and a sense of repetition to the walls that echoes both the horizontal rectangular detail on the sofa back pillows and the the geometry of the allover carpet pattern.
• In this example from Dwell, the rectangle that is accentuated as a decor detail is also an architectural one. By defining out the bookshelf recess in a bold color (that is a close match to the flooring) what would have simply been a "nice" detail becomes a full on wow.
• A classic way to add a rectangular shape to a room is used in this example from Elle Decor - an oversized folding screen (made up of 4 smaller rectangles, naturally) is finished in an amazing peacock blue gloss. Adds tons of color and instant spacial depth in one fell swoop.
• The power of the rectangle doesn't get any easier (or more impressive) than when it is introduced into a room otherwise comprised of curvy, biomorphic forms. Everything else in this room from Metropolitan Home is flowing and rounded - including the painting within the hard-edged frame.
