“Most designers agree the secret to a well-appointed mantel is asymmetry. But that’s not always immediately achieved. In fact, Interior designer Adam Charlap Hyman of AD100 firm Charlap Hyman & Herrero recommends starting with symmetry. 'To start, arrange the mantel in its most formal, original state—completely symmetrical. Starting from the edges, add in anchoring items that come in a pair—like a set of lamps or candlesticks—and then begin to work your way in.' Once you’ve established your base layer, you can begin to 'dishevel it a bit,' as Hyman puts it—adding in those imperfect touches that make the arrangement feel lived-in and effortless.”
