Simthread Embroidery Machine Thread 6 Colors Glow in The Dark Thread (1000Y)

Used on the moon on this black towel. No problem with my machine and it really glows.

I tried all needle types and sizes from 11 to14, microtec/embroidery/janome pink and blue/metallic, best combination was the janome Pink needle. I have a janome 550E machine, speed slowed down to 500 and the white and grey threads worked best with few breakages.However, ALL of the other colours shredded and broke at the needle eye after only150 stitches on average, so pretty much useless. I would not buy these again as the quality between spools is very wide ranging an unpredictable. I did manage a snowflake in all white ok though, only 10 breaks in 35,000 stitches. Overall not worth the expense or wait, very disappointed.

They don't glow in the dark well but if you use a black light on them they glow amazingly. I use them in combination with uv reactive string to do cool affects with string art.

Love the variety of colors and versatility of this glow-in-the-dark thread! Used the pink, blue, and gray for the glow-in-the-dark cats and they all worked perfectly!

It glows beautifully. However I've been struggling with horrible thread shredding (almost 30) on a minimally dense 6x10 design. While the ship in the design appears dense, the breakage occurs even in the thinly stitched areas. I've changed needle gauges, tried thread conditioner, and changed the bobbin, but the thread continues to shred and break. I'll try another design and update my review of it performs better.
