I've auditioned reds, aquas, and neutrals without finding anything satisfactory. I considered doing applique with all the bright fabics in vines and leaves. That sounds like a lot of work and all it would do is draw your eye away from the circles again. That's not my goal.
I kept on searching and I found a Faye Burgos fabric by Marcus that has "potential". I have 6 yds. of it so I think I could us it for the border and the backing if I choose to.
Decisions, decisions. . .
