Now I have to wholeheatedly agree with Geoff. I DID use the Art of Kiltmaking as a guide to making a box-pleated kilt (before the supplement). I found it to be extremely useful. I had researched Matt Newsome's comments on the box-pleating and found that when I read the supplement the methods that I had used to construct my kilt were 99% identical to those in the supplement. I cannot say enough positive things about the book. You MUST have this in your library.
