Textile design is the process of creating designs for knitted, woven or printed fabrics. Successful textile designers marry a creative vision of what a finished textile will look like with a deep understanding of the technical aspects of production and the properties of fiber, yarn, and dyes. Designs for both woven and printed textiles often begin with a drawing or watercolor sketch of the finished design. Traditionally, drawings of woven textile patterns were translated onto special forms of graph paper called point papers which were used by the weavers in setting up their looms. Today, most professional textile designers use some form of computer-aided design software created expressly for this purpose.
