This is one the most common issues when people start sewing by using a computerized sewing machine or even the simplest one. Beginners and sometimes the pro also face this kind of issues. The most common cause of thread accumulation and stitch skipping is the wrong threading of your machine. If you have thread your machine through the wrong path or have not placed your thread correctly in its right place, the tension of the thread will be affected and it will not be pulled in, the way it should be. For this you should make sure that you don’t thread your machine carelessly without lifting up the pressor foot. As, if you do so, the tension controlling plates would not open, to accept the thread correctly. While if you make sure the pressor foot is not put down and you have got the machine in its right condition for threading purpose and the thread will get the desired tension and correcting flow to give you uniform, and steady stitches.
