Undercurrents (let the bones dry) is a multimedia piece which consists of an acid-etched copper bird sewn onto the acrylic-painted canvas with embroidery thread. The bird is 5.5in x 4.5in and the canvas is 16in x 20in. As the copper is not sealed, the remaining ferric chloride will continue to eat through the metal until the bird is gone and as such, all subsequent pictures of this piece will look different.
