This is located in a small sitting room immediately next to our kitchen. The sideboard provides needed storage, and the TV has to stay. Other decor is temporary. It has been suggested that I add a floating shelf(ves) to the space. Thinking black? One or two? If more than 1, should they be the same length? FYI, there is a black wall clock on the other side of the window, kitchen has black hardware island is SW Iron Ore. All thoughts/suggestions/criticisms are welcome.
