So here's the plan:
Using 2.5" x 5" (size when cut, now sewn) rectangles make oversized off-white and green chevron patterns.
This is in no way a perfect pattern, but at least you can get a very simplified idea. There probably won't be as many chevrons, and they'll be fatter.
The finished quilt will measure 62" x 76.5", requiring 279 off-white rectangles and 248 green rectangles!
