Thank you all for the compliments.

So how much fabric is in the 31 pleats? (Pleater)
If my sums are correct, 5.58m. I started with 8m and, after I had measured and marked, There was less than .5m left over! (This is how you manage to make a full 8 yard kilt for a 30" waist! Done by the usual rules you would be lucky to use 6 yards.)

NOT that I am really interested in doing one, of course. (Pleater)
Of course not, it's just an intellectual exercise, right?

I have a reproduction from What Price Glory and I love the swing of the kilt. But it is too hot to wear outside of Canada during the coldest winter night. (AtagahiKC)
The 18oz. works very well during the winter up here in the Great White North, but, once the temps. go much above freezing, forget it. The kilt that I made at the start of this thread (and this latest one) were made from 11oz. poly/wool. It is very comfortable now that we are in the hot, hazy, humid season. 13 and 16oz. should work well in more temperate climates, like, for instance, Dorset in the south of England. ()

Strangely enough, the light weight (11oz.) kilt also swings well even though it weighs a lot less than a military kilt. That is probably due to the extra material used. (And, the elastic ensures that the pleats all tend to move together.)
