This 4-ply fingering weight 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 and glows for an hour or more. The glow strength is stronger at first gradually fading to an after glow over time.
This is the coolest yarn for knitting, crochet, weaving and crafting! Cool crafts for kids who love the glowing affect! Perfect for knitted items worn outside & after dark for safety! Add to existing projects for super cool accents and outlines to your designs!
