When the living room feels over-arranged, this kind of abstract helps. It is a loose hand-painted grid, pale blue squares held inside a deep rust brown ground, and it does the job of one big confident gesture instead of five small ones. Hung up, it warms the wall and gives the eye somewhere simple to rest. It sits well above a sofa, above a low sideboard, or on its own on a chalky off-white wall in a hallway. Pair it with terracotta, warm leather, linen and mid-tone wood, and let one plant do the greenery. Don’t crowd it with busy patterned pieces or fussy small frames, and don’t hang it in a cold blue-grey room where the rust has nothing to answer to. As a canvas, the painted surface reads as a real painting from across the room.
