Fiber art refers to fine art whose material consists of natural or synthetic fiber and other components, such as fabric or yarn. It focuses on the materials and on the manual labour on the part of the artist as part of the works' significance, and prioritizes aesthetic value over utility.
The term fiber art came into use by curators and art historians to describe the work of the artist-craftsman following World War II. Those years saw a sharp increase in the design and production of "art fabric." In the 1950s, as the contributions of craft artists became more recognized—not just in fiber but in clay and other media—an increasing number of weavers began binding fibers into nonfunctional forms as works of art.
The 1960s and 70s brought an international revolution in fiber art. Beyond weaving, fiber structures were created through knotting, twining, plaiting, coiling, pleating, lashing, and interlacing. Artists in the United States and Europe explored the qualities of fabric to develop works that could be hung or free standing, "two or three dimensional, flat or volumetric, many stories high or miniature, nonobjective or figurative, and representational or fantasy." The women's movement of the same era was important in contributing to the rise of fiber art because of the traditional association of women with textiles in the domestic sphere; indeed, many of the most prominent fiber artists are women.
Since the 1980s, fiber work has become more and more conceptual, influenced by postmodernist ideas. For fiber artists, in addition to long-standing experimentation with materials and techniques, this brought "a new focus on creating work which confronted cultural issues such as: gender feminism; domesticity and the repetitive tasks related to women's work; politics; the social and behavioral sciences; material specific concepts related to fiber's softness, permeability, drapability, and so on."
Modern fiber art takes its context from the textile arts, which have been practiced globally for millennia. Traditionally, fiber is taken from plants or animals, for example cotton from cotton seed pods, linen from flax stems, wool from sheep hair, or silk from the spun cocoons of silkworms. In addition to these traditional materials, synthetic materials such as plastic acrylic are now used.
