Koenigsberg has a rich history of study and work in all things textile. She founded a custom design needlepoint business that thrived for many years in New York City. Then with a desire to focus more on her own work, she closed the business and became a student again studying for three years at The New School for Social Research. Her studies there were life-changing and set her on her present course. To ensure the continuation of an artistic exchange, she and fellow students began the Textile Study Group of New York in 1977, holding monthly meetings for lectures, presentations and demonstrations. They invited artists from around the world whose work was well-known and well-regarded internationally to present their work. Occasionally, presentations of historical importance or technical expertise were invited ensuring group members of a broad range of knowledge from ancient to the most contemporary textile practices. Koenigsberg is today President Emerita and still deeply involved in the group's ongoing programming.
Koenigsberg has an extensive exhibition history in the United States, Europe, and South America and has completed numerous commissions. Her work is included in the collections of the Cleveland Museum of Art, OH; Indianapolis Museum of Art, IN; Museum of Arts & Design, NY; Museum of Fine Arts, Houston, TX; Racine Art Museum, Racine, WI; Textile Museum, Washington, DC; Sara and David Lieberman Collection, Tempe, AZ; and many additional private collections.
