There are a number of reasons why sewing needles fail.Quality varies widely among brands. An inexpensive needle might not last as long as a high-grade needle. Buying needles from a reputable company may solve the problem.Sometimes, the needle a user installs is not the right needle for the task. Size matters, as does the nature of the material to be sewn. A heavier material could cause a weaker needle to snap.If you don’t replace your needle soon enough, it will fatigue and break. Some experts recommend replacing a sewing needle after 16 hours of service.
