Double Quarto Pin - small flame-colored folded copper brooch

The quarto pin is a small, elegant, three-dimensional pin calling to mind books, leaves of paper, and origami, without being directly representational (like our Book Pins). They are created by folding two pieces of thin copper sheet once, then beginning a second fold, leaving them with a curled shape. The two pieces are set next to each other and attached to a nickel pin back. The coloring of the pieces arises from heating the copper to make it malleable after the first fold, and is a natural effect. Colors range from reds and oranges to browns. Most can be worn either way up. Pins are sealed with acrylic fixative to preserve the color and keep it from affecting clothes.
