Fiber Arts is a broad category that includes every aspect of textile construction. From plying and spinning wool to make yarn, dyeing the yarn. Then weaving, knitting or crocheting the finished yarn into a fabric. Fabrics can be further cut and sewn, quilted, and embroidered to create a finished object.
Paper and books are often included in fiber arts because of the use of cotton and other plant sources for linters to make paper. Construction of books also involves hand sewing techniques and can be utilitarian or decorative.
