Review on 🧵 SINGER Clear Invisible Thread 135 Yard Sewing - Ultimate Solution for Invisible Stitches by Carrie Spencer

the thread kept getting caught in the notch on the spool; a notch to prevent the thread from unraveling when not in use. Even though I put a groove on the back of the spindle, away from where the thread enters the machine, the thread kept catching on it and breaking. I tried filing the notch and making it flush with the spool but that didn't work. I sewed a few inches, then the thread caught and broke. I bought a different kind and threw that one away.
