Similar suggestion ....
... you have the white sashing edge already. Then your rust (double the width of the white), then an insert of the green or another fabric (same width as the white, or perhaps narrower) and then more of the same rust (1-1/2 or double the original rust).
Then bind in the rust ... or perhaps a scrappy binding of your leftovers!
