I just remembered - want to warn everyone - if you use the directions in the book, you should be aware that the yardage requirements seem to be based on fabrics that have 44" usable width. I did my usual spreadsheet before starting, using a 40" usable fabric width, and found that the estimates in the book (for yardage and number of strips of each size) were often inadequate. You should plan on needing more fabric, and cutting more strips.
