Pleating to the stripe or stripes.

[M. A. C. Newsome]

I had a MOD Hunting Stewart, pleated to the yellow and red stripes alternating ... looks like I took the pictures offline, though.

The Hunting Stewart, when pleated to stripe, is almost always pleated this way, because of the extremely large size of the sett.

I've seen other tartans pleated to alternate stipes as well. It works no problem.
