The most popular materials for crafting handmade robes are natural fibers such as silk and cotton. Because silk is a light-weight, water-resistant fiber, it provides the wearer a sense of luxury and comfort. Rayon is a natural-based material made up of an organic compound derived from cotton extract or wood pulp. This fiber is extremely durable, breathable, and cost effective. Cotton is celebrated for its comfortability and elasticity, and it provides excellent insulation. These fibers make for garments that exude luxury and relaxation.
