This yarn is great for all kinds of craft projects. It is white in color but glows green in the dark. Charges best with natural, full spectrum, fluorescent, or black light. Takes only a few minutes to charge. The glow strength is stronger at first gradually fading to an after glow over time. To test the glow expose the yarn in direct sunlight for 30 seconds then immediately take into a dark area.
