i'm not sure yet. i might do it in bright scraps on Kona white.
I just finished an EPP 2" 60 degree diamond in aquas and blues, and a dog bone in 1" hexes. all brights on white. I'd love to post a picture of them, but i read someplace once we post a photo, it's the QB's to do whatever they seem fit to do.
If this information is incorrect, someone please tell me.
