"Hiring an interior designer will give you access to a large selection of to-the-trade-only furnishings, fabrics and wall coverings that otherwise you’d probably never see, and the services of workrooms and tradespeople that the designer has cultivated relationships with over the years."

"Working with an interior designer can be costly. It’s also a very intimate process. You will be sharing a lot of details of your life with another person."

"Hire a decorator by the hour to help you plan the layout and the furniture, fabric and color selections, then execute the plan yourself. Not all designers are willing to accept small assignments like this, but some will welcome it."

"Work with a virtual designer. A growing number of designers have hung their shingles on the Internet. You send them photos or a floor plan of your home, and they provide consultations for a fee, without ever meeting you (or your home) in person."
