Let me explain.
Problem: Thread would get caught and pull ending up in breakage while sewing. I brought pictures along to help show what I mean. You know the little notch where the thread is stuck into when you first purchase it? That is what my thread kept getting stuck in!
Solution: Now this is quite simple; when you sew, turn the notch to the opposite side of where the thread will be pulled! No more breakage while sewing :)
