This is the textbook you'll need for Fundamentals of Interior Design at Heritage School of Interior Design in Denver.
The person before me highlighted a bunch in chapters 1-3 but lost steam after that =). You don't need any of the online/workbook stuff that Amazon will try to sell you, just this text.
Available the last week of March for the term starting April 9.
