ORDER MANDATORY FOR A COLLECTOR. The best advice for collectors of medium-sized things, whether cat figurines or pebbles of an unusual shape, is to keep them grouped in one place, and not randomly placed around the room. Chaos from little things can spoil even a very decent interior. BALANCE OF LIGHT AND SHADOW. In many ways, the appearance of a living room is determined by how balanced light and shadow are in it. Therefore, proper illumination is very important. For example, for the convenience of staying in residential lighting, a multi-level layout of lighting fixtures is mandatory. Lighting also affects the perception of colors. REMEMBER MIRRORS. A mirror is not only a reflective surface, which will help to make sure that everything is in order with the appearance. It is also a decor that has almost magical properties. Mirrors visually increase the space, make it brighter, airier and more refined. Decorators never forget this in the process.
