A clarification Alan.

The large sett of 9 inches was a rough estimate of the #3 Tartan done way back when we were still in the planning and voting stage.

I don't think we ever calculated for the sett of the #1 or #2 tartans.

The differance here is not due to design, but due to yarn thickness. The Merino wool that Fraser & Kirkbright uses is a much finer wool than say Locharran.

This resulted in a significantly smaller sett than is usual for Kilts. (under 4")

This adjustment of thread count needed to be done to bring the sett back up to a usable size of 6-6 1/2".
