What can I make with these beads?

[seeker]

I have 10 lovely iridescent glass rings, about the same size as polo mints but with a slightly bigger hole. I also have some lovely blue suede leather cord. What can I make? I've just threaded 3 other ones onto a cord and made a necklace, and I like it a lot, but I'd really like to try something a bit more complicated. Any ideas?

Double the cord, then thread each bead throughone cord one way and the other cord the opposite way, then tie a knot in both cords together, then thread the next bead on and knot and keep going, finish off with a clasp at the back for a nice necklace.
