The 1960s saw some of the most important works produced during Abakanowicz's career. In 1967, she began producing three-dimensional fiber works called "Abakans". Her "Abakans" were included in a group exhibition titled, "Wall Hangings", organised in 1969 at the Museum of Modern Art in New York by Mildred Constantine, curator of architecture and design, and the textile designer Jack Lenor Larsen. Abakanowicz and the other artists included in the exhibition were pushing boundaries between high art and traditional definitions of what was considered craft. Her use of "unexpected, often soft materials, arranged in modular or serial structures” in her "Abakan" series, places her within the Postminimalism art movement that began in 1966. Abakanowicz stated that she sought the “total obliteration of the utilitarian function of tapestry” and demonstrated the capacity of fiber to produce forms that were soft yet structured and complex.
