I gave this Superior Threads NiteLite Extra Glow thread a try for use as a dreamcatcher on a 34mm paracord covered split ring. I blunted a large sewing needle, on a diamond file, to help with feeding the thread over/around the loops when making it.
Being 30wt polyester thread, it turned out okay as a pendant to hang on a necklace or from the truck's rearview mirror, but it's not strong enough, like the 0.9mm nylon cord, to be used as a fob or lanyard. Maybe if I twisted 3 or 4 strands of it together, like a rope, it might then work... That's would be a lot of extra work, but still something different to try adding to various paracord projects.
The glow is actually not bad considering how thin the thread is and the package info said it will glow for at least 6 hours. It was still visible after that when I hung it from a nightstand lamp to test it.
