I began by transforming my own house, room by room and eventually started helping neighbors transform their houses. Today, because of word of mouth, I have a small business where I enjoy helping others with this transformation. I begin with what they have lying around their house, and work with their style and budget to help them transform their houses into homes.
Start a room with a piece of your favorite art. It will have a feel about it, colors you can coordinate your room around. Then fill in with the wall color, rug, pieces of furniture, and finally the accents!
