Anyway - I've always struggled with metallic-type threads on my sewing machine.
When Dawn asked me to do the demo ... I had to figure this out and make it work and I did!
The thread needs to be horizontal. Spinning off in the correct direction means no "extra twist". That alone made a big difference. Slowly down also helped. I tend to drive too fast. And tension - back off the top tension on these threads and life gets a whole lot better.
I quilted 2 (TWO!) of the Christmas tree wall hangings with silver metallic glitter thread and it did not break even once!!
