I emailed UKAHT last summer, and they said they would be happy to sell yardage for kilts. Just go to their site (http://www.ukaht.org/shop.htm) and send them an email! As far as I know, DC Dalgliesh does the weaving, and it's only available in 11-12 oz. Makes up into a nice lightweight kilt, though.

Cheers,
