began cutting paper in 2012 while working on her Master’s in Elementary Education at The University of Pennsylvania. When asked to create a children’s book as part of her program, she looked to Eric Carle and Ezra Jack Keats for inspiration. Building on the education she received from painting with her grandmother, Jacqueline Ziegler, and her time at the Instituto Superior de Artes de La Habana, Leff created her first papercut illustrations.
Leff has served on the board of The Guild of American Papercutters (GAP). In addition to being a GAP member she is a member of The Paper Artist Collective. Leff has exhibited her work throughout the United States, in China, and in Mexico. Her work has been acquired by The Canton Museum of Art (Canton, OH), The Colored Girls Museum (Philadelphia, PA) and The Museum of International Folk Art (Santa Fe, NM). She is the recipient of a 2021 Maryland State Arts Council Independent Artist Award, the 2021 Municipal Art Society of Baltimore City Artist Travel Prize, and the 2023 360 Xochi Quetzal BIPOC Residency. Leff resides in Puerto Rico with her husband and chihuahuas, Chalupa and Refrito.
