Remember that frit paddle/tray that I mentioned? These are the beads ...
OK, it's a crappy photo - taken with my phone, but they turned out rather well. They are variously fire lotus frit on a background of some black, some dark silver plum, and some on ivory.
Maybe the key to frit is keeping it in a flat, even layer.
Won't that be a pisser if I've been doing it wrong all these years? ;-)
