As smooth and shiny as silk, bamboo fiber adds a lustrous finish to yarns like Santolina, our fingering-weight yarn in a mix of cotton, hemp, and bamboo. Rayon from bamboo comes from the stalks and leaves of bamboo plants, which are broken down and spun into fibers. Bamboo is quick-growing and requires little water to grow, and its fibers are cooling and moisture-wicking, making bamboo yarns great for summer knitting!
