Due to the manufacturing process, can trimmings only be made with natural fibers such as cotton and silk?

Trimmings can certainly be made from a variety of materials beyond just natural fibers like cotton and silk. While natural fibers are commonly used for their aesthetic and tactile qualities, synthetic fibers such as polyester, nylon, and acrylic are also widely used in the production of trimmings. These synthetic materials offer benefits such as increased durability, resistance to wrinkling and fading, and often reduced costs in manufacturing.

In addition, the versatility of synthetic fibers allows for a broader range of textures, colors, and designs, which can be crucial for achieving specific aesthetic goals in interior textiles. Thus, the statement that trimmings can only be made with natural fibers is not accurate, as manufacturers leverage both natural and synthetic materials based on the desired properties and applications of the trimmings in various interior design contexts.
