Cappello’s artwork is her way of honoring and demonstrating her respect for Native American heritage and the Western lifestyle. She was born and raised on a large cattle and sheep ranch in the Colorado high country. Many hours were spent exploring encampments and burial grounds collecting artifacts and arrowheads. She also learned to trap and prepare furs.
Cappello's pieces are close, museum-quality reproductions of the ceremonial and war shirts, wedding dresses, and horse masks produced in the late 1800's and early 1900's. They feature fine beadwork, done in the traditional lazy-stitch technique, and authentic adornments as originally found on period pieces. She has won numerous awards in the mixed media category, as well as artists' and people's choice awards.
