5 stars (Get It!) - This book reads like a friend whispering all the good advice and secrets of the interior design business in your ear. I wish my Professional Practices class had used this text. It's a lot of information but Christine Piotrowski truly takes you by the hand and lets you know what you need to prepare for in a budding interior design business as well as how the interior design business is done in general. I will be referencing this book again and again. A huge thank you and bravo to Christine Piotrowski 5 stars (Must Have!) - This book was used for both Business Practice For Interior Design & Sales and Marketing. I had no need to consult any other source. "This is a great book" THANKS.. 5 stars (Fantastic!) - Outstanding, fabulous, fabulous book. Extremely helpful to me in starting my own firm. Well written.
