Sorry for the misunderstanding.

This is not a question about making the kilt. I have made mine so not as concerned about the pleating. I understand how the number of pleats, depth of pleats, and waist measurement work. I am just trying to understand how the linear material measurements and the finished kilt relate.

I want to be able to tell someone that it is an 8 yard kilt and know that it truly is an 8 yard kilt.

To sum what I am trying to confirm:
an 8 yard kilt = 8 yards of 28" OR 4 yards of 54" split and joined (8yds total).

a 4 yard kilt = 4 yards of 28" OR 2 yards of 28" split and joined (4yds total).
