http://http://www.celticdragonpress.com/ a good reference is this book

http://http://web.archive.org/web/20041205073825/users.telenet.be/jbruyndonckx/kilt_making1.html Another good reference, but I still recommend the book.

Or, if you'd checked the top link in this forum, the X-Kilt instructions.

Incidentally, I did the same thing, started with a childs Kilt. I'm on #3 now, about to make my first adult kilt.
