The pin was made using a large round button, an old earring and some black cord.
I glued the earring in place and then wound the cord round tightly, glueing as I went. It is something that you need a bit of patience with and asbestos fingers as you have to work quickly before the glue dries.
It is important to finish off the back well, a piece of masking tape keeps the end of the cord secure until you can glue the ends in.
The rings are made in a similar way, I wanted them to swirl in the same direction, but you could make them spiral opposite ways for a similar effect. I used a pearl bead from an old necklace in the centre.
