I have been thinking about this since yesterday, as I really don't think this is that boring....just sort of delicate. But I just though of rick rack....the wide rick rack, if they still make it. I can a crisp white border, as others have suggested....or maybe even a border with a white, pink, and blue pattern, but with rick rack on the inner and outer edges of it. I "think" that might look good. The rick rack would need to be pink or blue or maybe both....
Well, just a thought, in case it works for you. The quilt has no WOW factor, but not all quilts need that.
