Kaersten creates mixed media three-dimensional artworks constructed from a combination of organic and industrial materials. Her work is fueled by her interest in traditional folk medicine, folklore, and folk magic.. The works are not literal or narrative interpretations of these cultural practices; rather she combines materials such as human hair, beeswax and feathers, and traditional techniques such as metal casting, forging, and fabricating base metals to suggest or echo traditional folkways.

Some elements in the work are deceptive in their display. What might appear purely mechanical, domestic, or industrial at first glance, soon becomes sacred, magical, or ritualistic in character. The shift between these contexts holds her interests and encourages her to explore more ways of creating works that evoke feelings that are two-or threefold in nature.
