Start with about 18 inches of your favorite wire. I am using 16 gauge copper rose gold colored craft wire from http://www.wire-sculpture.com/16-gauge-silver-plated-copper-craft-wire . This seems half hard...I will use dead soft on my next one. Wrap it around your ring mandrel a little smaller than your desired final size leaving equal amounts on each end. Grip the wire close to the mandrel and bend up at a right angle on each side.
If you measure the distance between the holes in your focal...in this case a raku button by www.wondrousstrange.etsy.com and wrap your wire to match the approximate width the button will slide directly onto the band and rest properly.
Make a bend at equal distances above the surface of the focal and cut the wire with your side cutters.
Then curl up the wire into a fern frond like spiral. Since I used 16 ga half hard wire this was a bit tough and the marks from the pliers show.
When you curl the second piece..other patterns are ok..make it your way; make sure the spiral goes in the opposite direction.
Then carefully flatten the coils to the surface. This is where I discovered why dead soft wire would be best. A better spiral or other pattern could be made with soft wire.
All that's left to do is wear it.
