I know that kilt making is not rocket science. And, I can do Fahrenheit to Celsius conversions, and simple Trig in my head, but this is all starting to sound a little confusing. My waist size and my hip size are nearly the same. measured at just about the naval and at the widest point of the hips. Both are between 47 and 48 inches. So, if I understand it, an "8 yard kilt to fit properly on me would actually have around 9 yards of material?
