I used a sharpie to outline the numbers, then handpainted ours. If I had been thinking ahead I would have used fabric and iron-on bonding, then sewed around the numbers because I think it would have looked better, but we wrapped our bumpers before adding numbers. Be careful with spraypainting the already-covered bumper, because it is really easy for spray paint to bleed under stencils. Although it's ship day already, so I hope you've already figured this out. Good luck!
