Wire wrapped, using copper wire. I use copper because I like the fact that it darkens and can be antiqued. You can clean your jewelry with a soft toothbrush using, Wright’s Copper Cream, Twinkle or King Kleen copper cleaner or any cleaner designed to clean copper. The darker pictures are more accurate. I made the images lighter so that you could see the detail better. The piece can be made more light copper with the above cleaners.
