These are made with copper wire.  I had made some square wire for an earlier project, but it was a larger gauge, so I rolled it through the rolling mill to make it smaller.  Bending the square wire without twisting it was challenging.  I decided to patina the copper with liver of sulfur before adding the aquamarine beads in two different shades.  

I want to thank you, Joanne, for all the new designs which are both beautiful and have been educational!
