Lesley Haas was born in Philadelphia, Pennsylvania and has made her home in Heidelberg, Germany from 1988 until 1996 and from 1999 - 2000. Since September, 2006, she is again living in Philadelphia.
She developed an interest in handmade paper after viewing a comprehensive exhibit in which the artworks were made with paper in New York City. She is an active member of the International Association of Hand Paper Makers and Paper Artists (IAPMA). The signature of her work is the use of natural fibers and pigments from various parts of the world to blend the characteristics of the fibers with different elements of style. As an extension of her papermaking she has created artworks from fibers such as flax, cotton, sisal, African fiber and vegetable papyrus. In addition to works that are formal explorations of these fibers, she has made objects ranging from dresses, shoes to goblets, pointe shoes, and bottles. In recent years, she reused packaging materials, magazines, and all types of paper in developing a scrolls series.
