Woven fabric is formed from two sets of threads such that all the threads in one set are parallel to each other and perpendicular to all threads in the other set. The set of threads which run the length of the fabric is called the warp; the set of crosswise threads is called the weft. These two sets of threads are interwoven to form a mesh which is called a web. The design of a woven fabric originates with an artist's sketch. Since the threads within each set remain parallel to each other, any curved or non-rectilinear lines in the artist's sketch must be represented by series of vertical or horizontal line segments in the woven fabric. Therefore, the fabric design is an approximation of the artist's sketch. The finer the web, i.e., the more threads per inch, the better the approximation will be.
