NiteLite ExtraGlow is a fun, creative thread for quilting, embroidery, and decorative stitching. It is popular for children's pillowcases, blankets, quilts, and pajamas. Available in 6 colors. Expose it to light for 30-60 seconds and it will glow for hours. NiteLite can be recharged over and over again without loss of glowing effect. A dense stitch pattern will provide a better glow than a single stitch. Be creative in your next project and add some glow-in-the-dark NiteLite for a glowing effect.
