I think if it were me, I would put a New York Beautie using three sides for corners and then putting a half over the fairies. I do not know your dimensions, but that would put it large enough for the bed. I would then put a simple border to frame it the rest of the way but being sure to miter the corners. Using the floral fabric as the ouside border would be nice and making the NYB in the green and blues. I would zinger it with that dark blue or maybe introduce a dark green/blue color to combine the two. It will be a bit more work, but I think it would compliment the center.
