Memory wire is rather fun, because it so easy to use.
Just string beads on, and finish the ends either by gluing on a
memory wire end, or by using durable round-nose pliers to twist each end into a loop.
You can even add dangling beads or charms to looped ends, but that might be overkill on a ring.
A good ring is normally 3-5 loops of wire. (An ounce is about 200 loops, so you can make a LOT of rings with one ounce.)
Wow, we don't have any pictures of memory wire rings in our gallery! I'll see if we can fix that soon. In the meantime, here are a few pictures that give some ideas.
This "Peppermint Pattie" bracelet uses the round memory wire ends:
