Knife pleated kilts: 4 yds vs 5 yds

[billmcc]

I think that some of it might be advertising, but the terms 4 yd, 5yd, 8yd, etc. are really more averages than actual specific lengths of fabric. At least I think that is the case. And if not, I need to re-read Barb's book!

I understand the yardage of a kilt is based on averages. I am wondering if a 4-yard kilt lacks something that is present on a 5-yard kilt.
