All the kilt makers on this forum.

Note esp, the edges of the apron and the angles of the front side pleats.
DO NOT skip on the underapron pleat, it WILL be missed if you don't do it.

I STILL push Barb's book, if can fork over the $30 to one who sells it. It is MUCH better than any of the linked sites above in both detail, helpfulness, and completeness.
