Why does my bobbin thread not catch?

Why does my sewing machine not pick up the bobbin thread?

First, make sure the bobbin-winding spindle (located on top of your machine) has been pushed back to the left for sewing. If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … If the timing is out, the needle thread is not meeting the bobbin thread in time to form a stitch.

What do you do if your bobbin thread won’t catch?

Your Needle Is Not Inserted Correctly

If your needle is not being held in all the way, it won’t be in the right place to grab your bobbin thread. Make sure your needle is inserted all the way up and tightened as much as possible. Also, make sure not to insert your needle backward on your sewing machine.

Why is my thread bunching underneath?

A: Looping on the underside, or back of the fabric, means the top tension is too loose compared to the bobbin tension, so the bobbin thread is pulling too much top thread underneath. By tightening the top tension, the loops will stop, but the added tension may cause breakage, especially with sensitive threads.

Why is my upper thread getting caught in the bobbin?
