What cause thread breakages

Thread Breakages

Just sure before you start to sew, make sure the fabric is place under pressure foot. Just like if you was going to use a regular sewing machine. (only when you going to cover stitch) I used polyester thread. I found when I use 100 precent cotton thread or silk; it break easier; or could be the thread is too old. Some sewing supplies stores that sell thread that don’t have a plastic cover around it, you made have to test it to see if not weak. Also make sure the tension on thread of the machine is not loose or tight, all these possibilities it’s what cause thread breakages.
