What Brooke said.
And, I'd encourage you to at least talk to a stateside kiltmaker. Call Matt at the STM or any of the other kiltmakers here and get their opinions. They might be able to order an extra yard-and-a-half of your tartan which you could fringe yourself and have the fly plaid at a lower cost than hiring someone else to fringe it for you. That's what I did.
And do keep us posted, whatever you decide.
