Sett size and bow ties

[Mikilt]

Hello Rabble,
I make my own bow ties and I am considering making one in the Xmarks tartan. The problem is that I can't quite fit the elements of the tartan onto the pattern. Basically, it would just look like a blue bow tie with white stripes on one end. There is either no grey or no white.

Is there a way to "shrink" a sett? Like so that I can get several sett repeats on a smaller piece of cloth? I realize that I am talking about getting a piece of fabric custom made/printed. I am just wondering if a sett can be shrunk.

Example: the background here on XMarks size. If I could get it printed as is on a piece of fabric, I think it would make a great bow tie.
