I've always liked the look of the larger sett sizes. They look more dramatic to me. I knew from some of his posts that Matt was a fan of them also. So when it came time for my next kilt, I decided to order a 12" sett kilt from Matt. I believe that the normal Mackay sett size woven by Lochcarron is 7". I think that the larger sett size really helps the kilt stand out, especially with such a muted, dark colored kilt.
