Q: I recently purchased the fluorescent white machine embroidery thread and i sewed my design and exposed the item to direct sunlight for 8-12 hours and it does not glow in the dark. What do I need to do to make it glow in the dark?
A: Madeira Classic Rayon #40 - 1100YD Mini Snap Cones - Color - 1005 - Fluorescent White (This is not Glow-in-the-Dark)
It is called Fluorescent because it is Shiny/Bright.
