Interior decorators use their artistic skills to design appealing spaces. You'll be spending lots of time with your designer, picking out everything from floor to ceiling. The decorator makes sure all the elements work together for the desired impact of a room. Among the things an interior designer will help you pick out are flooring, cabinet handles, counter tops, furniture, wall covering and lighting. Decorators sometimes have assistants who do the actual work of redoing a room. Most interior decorators specialize in certain areas of home design, like kitchens or baths. You'll have to find one who crosses those lines if you're looking to redo your whole house. Decorators have to be knowledgeable in local building codes. Most have a bachelor's degree, and some states require them to be licensed and have passed a skills test.
