Why is my needle not catching 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.

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 bobbin not winding?

If your bobbin does not wind quickly and smoothly when you press on your foot pedal, your bobbin winder might not be fully engaged. This can cause uneven winding. Make sure you push your bobbin pin all the way over or loosen your bobbin wheel completely to engage your bobbin winding mechanism.

What tension should I use for cotton?

The thread should unwind just slightly and the bobbin case should drop an inch or two. If the thread unwinds without resistance and the case slips to the floor, your bobbin tension is too loose. If the bobbin case doesn’t budge, your bobbin tension is too tight.

What tension should I use for thin cotton?
