NiteLite is a 40 wt. polyester thread that glows in the dark for up to six hours. The white NiteLite thread glows brighter and longer than the other colors. To get the best glowing effect, it is necessary to stitch a lot of thread in the area intended to glow. A simple meandering stitch will not be visible. We recommend filling in an area with embroidery, free motion quilting, or a satin stitch. The denser the stitches, the brighter and more prominent the glow will be.

Before using, test the thread by exposing the thread to either a bright light inside or direct sunlight for 30 seconds, then take it into a dark place and see how bright it glows.
