vmac3205 does good work in everything she touches. You can also find a local tailor who will be able to do the job with a little coaching, as mentioned above. It doesn't cost much, and the turn around is pretty quick.

If you have a copy of So You're Going to Wear the Kilt, there's a page in the back about doing exactly that, as I recall. You can also just show a few pictures and wear your kilt for the tailor to mark it, and you should find yourself pleased as any competent tailor can do it.

Slow photos when you get it done.
