Lighting is a key factor in designing and should always be a primary focus of thought for all of your interior design plans. Soft, translucent lights create a warm, personal environment that is ideal for areas such as living rooms or sitting rooms.These types of areas are also great for bedroom lighting arrangements as well.
Wall treatments are another key element to interior design. If you are unsure of a color, before actually painting the walls, paint a large piece of cardboard and place it on the wall next to a window or other architectural piece in the room to see how the color lays.
Lighting choices and placement can make all the difference in the world in a dark room. Introduce low wattage lamps into the space to warm the room up a bit.
