Natural fibers used in sewing primarily come from what sources?

Natural fibers used in sewing primarily come from two main sources: plants and animals. Plant-based fibers include cotton, linen, and hemp, which are derived from various parts of plants, such as seeds, stems, and leaves. Animal-based fibers, on the other hand, include wool from sheep, silk from silkworms, and cashmere from goats. This combination of fibers allows for a wide range of textures, durability, and uses in sewing and textiles.

The assertion that natural fibers originate only from animals would ignore the significant contribution of plant-based fibers, which are equally vital in the textile industry. Similarly, chemicals and synthetic materials represent entirely different categories of fabrics that do not fall under the definition of natural fibers. Hence, the broad inclusion of both plants and animals captures the full spectrum of natural fibers utilized in sewing.
