Went to a Metal and Glass symposium and took a class on wire finger rings taught by Master Philippe de Lyon. The handout was based on pages from the book Dress Accessories, c.1150-c.1450 (Medieval Finds from Excavations in London).

These are the two rings which I made during the class. Simple, cute and the seem to fit my daughters perfectly. These are the only two which I’ve attempted to make, but I can see working on some other variations in the future.
The ring on the left is made from silver plated wire and a red coral bead. The one on the right is made from antiqued brass wire with a fresh water pearl. I understand that the instructor purchased all of the supplies from Hobby Lobby and each ring costs less than a few dollars when supplies can be found on sale.
