ambrose, I don't know about that pattern, haven't seen it, but I know Folkwear has one that's supposed to be very good. www.folkwear.com
I'm making my third kilt now and I just used the info on a couple websites as guidance. They come out fine just measuring. After all, you'r biggest job is the pleats. Once you figure out the width of the pleats and the depth you can make a template that speeds it up. It takes time for us rookies to do it, but a bit of patience is cheaper than the price of a kilt
