The reasoning behind identifying fabric as the material that is not classified as hard is tied to the properties of the various materials listed. Hard materials are typically characterized by their rigidity, strength, and the ability to resist deformation. Glass, wood, and metal all possess these hard qualities to varying degrees; they can withstand pressure and maintain their shape when subjected to force.

On the other hand, fabric is inherently soft and flexible, designed to bend and fold without breaking. Its primary characteristics are its pliability and comfort, making it unsuitable for classification as a hard material. Fabrics are used in applications where softness and flexibility are desired, contrasting sharply with the rigidity provided by hard materials like glass, wood, and metal. Understanding these properties is essential for interior decorators, as the choice of materials greatly influences the aesthetics and functionality of a space.
