Place the Ollipsis shelf on an area of the wall where it will not impede comfortable passage into and around the room. Don't place it too close to a doorway, for example.
Place your tallest items, such as taper candles or shampoo bottles, on the top shelf. Other items, either decorative or frequently used, such as soaps, containers of bath salts and oils, makeup or even washcloths, can go on the two lower shelves.
Keep the shelf clean. Remove items from it weekly and use a soft cloth saturated with rubbing alcohol to remove grime and polish the chrome, as the experts at Reader’s Digest suggest. In between weekly cleanings, dust the shelf if necessary, using a soft lint-free cloth.
