Alva there is no toning this vibrant beauty down!
Personally, I'd love to see it with a black and white stripe edging. I think that would have enough pizazz to work with the dynamic, colorful quilt you've made. The turquoise alone would work too but forgive me folks... it just seems a touch uninspired at this point.
Can you imagine walking thru a bland, sterile hospital and then seeing this on someone's bed vibrating with color and vitality? I think your quilt is truly inspired... take time with options for it. It's going to make someone feel love and alive.
