Broken upper thread is one of the most common errors when using a sewing machine. This problem not only causes inconvenience but also affects the quality of the seam. So what are the causes and how to fix this situation? Let’s find out through the article below.

Causes of broken sewing machine thread:

• Sewing machine needles: Blunt, broken, wrong size or incorrectly positioned needles can all cause thread breaks.
• Sewing Thread: Thread that is too tight, too thin, poor quality, or tangled are also common causes.
