I have only one SWK Heavyweight, a size 38 black shadow. The material in it measures 266" by 24" and the whole kilt weighs 54 ounces. Defining one fabric yard as 56" by 36" I compute 3-1/6 fabric yards at 17 ounces per yard. If you subtract the weight of the non-woolen materials, which I can only guesstimate, you will probably get about 15 ounces per yard.

I'm not going to debate the statistical significance of n=1, but I rather suspect it exceeds that of n=0. There really is no predicting where you're going to find an engineer, is there?
