Form in the textile art, as in all other useful arts, is fundamentally, although not exclusively, the resultant or expression of function, but at the same time it is further than in other shaping arts from expressing the whole of function. Such is the pliability of a large portion of textile products—as, for example, nets, garments, and hangings—that the shapes assumed are variable, and, therefore, when not distended or for some purpose folded or draped, the articles are without esthetic value or interest.
