Take their house and make it home. Find out how they really live and make it work for them. A throw at every sofa, make sense of their family photos and art collections. Framing and grouping etc. Taking a whole bunch of photos and making them all black and white and doing a gallery down a hall way.
Every phone has a pad and a decorative pen, every nightstand has a silver plate coaster for the water you carry to bed. Proper lighting so you never sit in a chair where you cannot read a book. Foyers have rules, a parson‘s table with a mirror over it, one small light, and a silver bowl to catch the keys and the sunglasses when you walk in the door, a candle and maybe a vase of flowers, and of course an umbrella stand.
Setting the bedroom right always starts with the bedding. I believe in white sheets with 2 stripes across the top for a color accent.
A duvet folded in thirds at the end of the bed with a white cotton blanket. Why do you think all the best hotels in the world have white sheets?, so they can use Clorox and get them clean and it is a status symbol.
I love to shop in someone‘s home and help them make sense of what they have and where the holes are and what pieces we need to shop for on a budget. Move lamps around and hang photos correctly. Figure out furniture so that it has a relationship to the things around it. Most people place the coffee table way to far from the sofa and they hang oils and photos too high.
