Juan Carlos Arango and Angela Matiz are Colombian wood carvers who use precious native woods leftover from wooden flooring, roofing, and industrial processes to create their winged mobiles. Ebony, Trupillo, Corazón, Guayacán, Nazareno, and Poui trees provide the woods, which the artists sculpt to highlight the grains, burls and colors. They finish each piece off with linseed oil to moisturize and seal the fibers. The definition of sustainable artists, they give their discarded wood to other local creators who use it to make jewelry and other accessories. Looking ahead, Arango and Matiz started a tree conservation and replacement project in Colombia to assure there is enough ground cover for a healthy bird population.
