I like the green too.... that's the problem, I like the green AND the yellow combinations. The red is wearing off, but I'm not really a red person.
On the other hand, the suggestion about doing just a thin border really appeals!
I managed to get more spot fabric, not quite enough but I should be able to fudge it. And I got some yellow and some green that matches perfectly while I was there.... despite still not being able to decide! LOL
