Yes, do read David again, he said that some times when the thread count is changed to much IT IS HARD TO ID THE TARTAN.......
That was my point. when you change the thread count, you run the risk of change to the tartan as it was designed, and have in fact plagerised the tartan and make something that it not... a number of your mates have read what they please and not what was asked.
The question was not how do you redesign the sett, it was how to make it smaller, the wt of the thread used will do that with out changing the sett GO UP
