I agree with Matt. And for the same amount of fabric (we're talking trad kilt here, 8 yard, for example), the pleat depth is not all that important. Lots of shallower pleats will swing as well as somewhat deeper pleats because the weight of the material is the same.

And Steve comments are really relevant, because his Freedom Kilts and the trad kilts that I make behave differently and the controls on behavior are somewhat different. So, Steve, get out from under your complex, you old curmudgeon you!!

Hogs and quiches,
