I did a similar lap quilt with a narrow red border, wider black border, and then the binding was the b/w print with white beads meandering which many thot set it off. I'll try to add a pic.
Love your colors, I would do a small black inner border then maybe t a red black outer border.
That would be my suggestion, too. I love this! All these red, black & white quilts really inspire me to leave my comfort zone & make one! This one is gorgeous!
