Reflective yarn is a special type of thread or string that can reflect light. It’s like having tiny mirrors on the surface of the yarn that bounces back light when it hits them. This unique quality makes the yarn highly visible in low-light conditions, such as at night or in dimly lit areas. It’s often used in clothing, accessories, and even outdoor gear to enhance visibility and safety. When light, like that from a car’s headlights, shines on the reflective yarn, it creates a bright and eye-catching effect, helping people and objects stand out and be easily noticed in the dark.
