It's very satisfying for a potential client to say that they have talked with several designers/decorators and they want to work with me. I don't pretend to know how other designers work, all I know is how I work and approach projects.
I have a new client that said, "I don't know what I want, I can't picture anything, so you bring me choice A, B, or C, like on HGTV." I think some other people she interviewed were overwhelmed by that statement, but I was thrilled. First, I have to listen really well to what the client wants, and read between the lines as to what personalities are in the family. By the time I left her house after an hour, I knew where I was headed for the style and design.
For someone that cannot envision where a design is going, I usually prepare a design board. The client can then see colors, textures, furniture tones, etc. all at one time. It becomes a road map so later on when that client runs across an accessory in "that green tone that was on the design board", they can buy it and know that it will work somewhere.
I actually like presenting a catalog of options to the client. Others may say that's way too much work, but honestly you need a place to start and it's easy for me and FUN. I love taking someone through the design process of, if A then B then C. As you flip through options you can narrow down someones style. I think this process for me is a combination of Candace Olson and Secrets of a Stylist on HGTV. I love doing this and I get paid for it!
