I have watched a couple of the HGTV shows -- including the ones by this pair. I have to say that I don't like what they do more often that I like the style. A friend of mine just had a decorator come in and she repainted the inside of her house grey. Now grey is great, but since that is the normal color of our skies and the decorator did not want even the little pops of color that would brighten it up, I sure would not hire that decorator.
My rugs and walls are beige because all of my accessories are full of color. We had to cover hardwood floors on the main floor because the bedrooms are below and it sounded like a herd of elephants walking around when some one was in the living room or kitchen and you were trying to sleep. Guess the decorating police would love to get me.
