Keep an open mind. It's a rare client who loves 100 percent of a designer's suggestions right off the bat. Your designer might recommend a piece of furniture or a wallpaper pattern that you're iffy about, but don't say no without giving the idea some time to sink in. Chances are that when you ask your designer why he or she chose it, and when you take a little time to live with it, you'll appreciate the reason it works. Look toward refreshing down the road. Even the best design doesn't stay current forever. Ask your designer if tune-up visits in the future are an option, whether they involve simply swapping out a few accessories, reupholstering furniture or choosing new paint colors.
