Unlike most abstract art, this doesn’t wait for approval. Four big blocks of rust, deep green, near-black and off-white sit against each other with no soft edges to hide behind. Put it up and the room stops feeling undecided. It gives a plain wall a centre of gravity, and it pulls warm and dark tones already in the room into some kind of order. Hang it above a low sofa, a sideboard or a writing desk, roughly at eye level, with plenty of clear wall either side. It sits well with leather, dark timber, black metal and stoneware. Don’t crowd it with small framed pieces or busy patterned wallpaper, and don’t hang it low behind a tall lamp. A black frame keeps the paper edges clean and sharpens the blocks.
