How do you know what tension to use when sewing?
The more thread in the stitch, then the looser the stitch. The less thread, then the tighter the stitch. Top thread tension is controlled by a dial on the machine’s thread path. So make sure the thread sits correctly between the tension discs when you’re threading your machine.
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.
