Description:
High light glow in the dark fluorescent embroidery thread is a unique kind of embroidery thread that produces light in the dark once it has been exposed to any light source, UV light, sun light, or natural light. This high light glow in the dark embroidery thread will absorb light during exposure time and then gradually release that energy to create a glowing effect at night or in low-light situations.

Features:
1. High light, glow longer time.
2. Polyester material, chemical-resistant, eco-friendly, high tenacity, low shrinkage
3. Goes on the machine very smoothly and doesn't break the stitches
4. 120 colors for selection

Using tips:
1. Runs on #80/12 or #90/14 Needle
2. Decrease embroidery speed.
3. It is coarser than normal embroidery thread and may not be suitable for small very fine embroideries
4. Adjusting tension is required, only adjust main thread tension.
5. Remember to let your project absorb the UV light, sun light, or natural light first, then go to a dark place. You will get a suprise.
6. Remember that the glow-in-the-dark effect will fade over time as the storage energy dissipates. Therefore, you will need to recharge the thread simply by exposing it to light again.
