I found the book, "Making Wire Jewelry" by Helen Clegg & Mary Larom which has the instructions for this piece and many other interesting designs. The book
includes actual size illustrations against which you can
compare the jewelry components you've made. I used 20 gauge copper wire. I think this bracelet would benefit from being antiqued. Rather than use the liver of sulphur method, I'm going to try using the hard boiled
egg method described here.
