How do you balance the bobbin tension?

If your machine has a top-loading bobbin with a nonremovable bobbin case, you can’t adjust the bobbin thread tension. Instead, balance the tension by adjusting the upper thread. Although you have less control, you can usually set the tension successfully by working with only the upper thread.

Why is my Singer sewing machine bunching thread on the bottom?

Thread looping on the underside of the fabric is always an indication that the upper thread is not correctly threaded. This happens when the upper thread is not correctly placed in the tension mechanism and has not been threaded through the take-up lever.

Why does my bobbin thread keep getting tangled?

Improper Threading

If your sewing machine thread is not properly threaded, the bobbin thread won’t be pulled up into the fabric the way it needs to be. Occasionally the upper thread can catch on a moving part or get stuck, which impedes the easy flow of thread through the needle, creating a tangle.

Why is the tension wrong on my sewing machine?

Needles, threads, and fabrics: Different thread sizes and types on top and in the bobbin can throw off basic tension settings. A needle that’s too large or small for the thread can also unbalance your stitches, because the size of the hole adds to or reduces the total top tension.

What number should tension be on sewing machine?

How do I stop bobbin thread bunching?

Your thread tension should be adjusted for different weights of fabric and thread. Make sure that you are using the same weight thread in both your bobbin and upper thread. If you don’t, your tension can be uneven and cause you to get bunched-up thread under your fabric.
