Kyle, I made a MacPherson Hunting kilt from cloth with a sett about that size -- and it was in Harris Tweed! I scored that length of cloth on Ebay. It was so nice I was tempted to keep it for myself, and I'm not even a MacPherson!

By the way, if anyone is desirous of a kilt made from tartan with a larger or smaller sett than usual, that is an option I can happily arrange for on my heirloom kilts.
