Design 101:

The elements of design are: space, shape, form, mass, line, texture, pattern, light and color.

What do you think the most important element is?  The answer might be surprising. 

The most important design element is LIGHT
Natural sunlight and artificial light affect the appearance of all other elements of design.    

How To Use Lighting in Your Design:
Balance overhead lighting with wall sconces, table and floor lamps for a softer, more relaxed lighting effect.

The ceiling fan light kit or the recessed ceiling lights are not the only light your rooms should have.
In addition to understanding how to balance artificial light, you need to understand how to manage the natural light.

Use window treatments that give you the option to control the natural light.  Options include cellular shades with top down/bottom up features, a multi-layered drapery treatment with a sheer bottom layer and a top heavier fabric layer and for a more modern look, solar shades that give you the ability to look out (darker tones) but block harmful rays.

Here are some other DESIGN BASICS to think about:

1.            Add color! Paint the walls (or wall).

2.            Mix & match eclectic pieces to create visual interest and personal style.

3.            Add an area rug to define open spaces.  An area rug will also add color and pattern to a space.

4.            Soften the room’s corner’s with plants…bring a bit of the outside in.

5.            Repeat accent colors through art and accessories.  Add new ‘life’ to a room by introducing a new accent color,using
colorful throw pillows and /or on window treatments.

6.            Arrange furniture in the center of the room away from the walls.

7.            Install new hardware on existing cabinetry (kitchen, bathroom, armoire, dressers)

8.            Balance overhead lighting with wall sconces, table and floor lamps for a softer, more
relaxed lighting effect.
