How do you start the bobbin on a sewing machine?

Why isn’t my bobbin thread coming up?

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.

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.

What is a bobbin used for?

A bobbin is the part of a sewing machine on which the lower thread is wound. The machine makes a stitch by catching the bottom thread, from the bobbin, with the top thread, from the needle.
