Kitchen or anywhere DIY. Seems simple enough, depending on your gap between shelves, anywhere from ropes to ropes for your spacing. You could even use wider wood, just adjust your rope length to accommodate your width and height of your shelves.
I love the idea of just a plain wood - even plywood - headboard. Very great interior solution for rental apartments and such where you don't want to make too many holes in the walls because you can hang art, or as in this case, night lamps onto the board.
