I have the book, and have followed it to make three kilts, and I'm working on my fourth, with plans for at least 4-5 more at some point in the not too distant future.

I skimmed it once or twice before starting, and got the jist of it, but didn't fully understand the process at first. However, when I started working with material, everything made sense. To say the book is a great buy is an understatement.
