Krouse was awarded a full scholarship to study at the Pennsylvania Academy of the Fine Arts. After graduating, she attended a woodblock printing course offered by Morris Blackburn, where she “fell in love with printmaking” and went on to create woodblock prints exclusively for the next 25 years. She often worked on a large scale and depicted flowers, leaves, and animals. She later developed a desire to use more color and eventually returned to painting, primarily in watercolor. Krouse’s work is in many collections, including the National Gallery of Art, Washington, DC; the Free Library of Philadelphia; Montclair Art Museum, New Jersey; the Reading Public Museum, Pennsylvania; and Woodmere Art Museum.
