Pleating challenges #1: dealing with a too-wide central stripe

[Barb T]

The narrow yellow stripe is the smallest element in the tartan, and it's 4 threads.

Oops - I didn't have my glasses on when I counted. It's 6 threads. But, you get my meaning. The sett would have been unacceptably small if they'd been able to reduce it by 1/3, and increasing it by 1/3 would have been a pretty big sett. I think they were pretty much constrained by the way the tartan was designed.
