Why does my thread bunch up when I start to sew?
It may sound banal, but particularly when you sew thick fabrics or several layers, you might forget to lower the presser foot. This of course means that there is no tension on the upper thread. The upper thread is pulled under, resulting in thread bunching.
Why is my thread shredding on my sewing machine?
The most common reason why thread shreds, frays, or breaks at the needle is because the eye is too small to accommodate the thread, causing stress and friction, which results in shredding or breaking the top thread.
How do you check if you have the proper tension setting?
To test if the tension is correct, insert a bobbin in the bobbin case. Then hold it up by just the thread, the bobbin case shouldn’t move. Give a little jerk on the thread and if the bobbin case slides down slightly, then the tension if perfect. If it drops freely, then it’s too loose.
Why does my thread keep snapping?
