Changing over from one embroidery thread brand to another is a common cause of embroidery thread breakage. The thread you use will make its own groove in the needle and when you change to another brand of thread it will not sit in position properly and you will experience thread breaks. Each brand of thread will be spun and twisted differently, so when you change your thread supplier the first thing you must do is also change the needles.
