I was going to say the same thing. It really does glow!
I'm not sure how it would look but you might consider making a narrow flange from the scraps you have left over & then adding a black border beyond that & then binding in black. Not sure if that would change the whole dynamics of the quilt or not. If that would not enhance it in any way I would just bind it as it is. It's very, very pretty just like you have it now.
