What should my tension be on my sewing machine?
The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing. This should be suitable for most fabrics. If you are doing a zig-zag stitch, or another stitch that has width, then you may find that the bobbin thread is pulled through to the top.
What causes my bobbin thread to bunch up?
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 evenly?
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.
When should I adjust the bobbin tension?
Hang the bobbin case by the thread. If the bobbin case doesn’t move at all when you jerk it the tension is too tight and you need to decrease the tension for sewing with this thread. If the bobbin case drops quickly the tension is too loose and you need to increase the tension.
How do I get the right tension in my threads?
Pull some thread off the spool in the machine and cut it close to the spool. Tie two or three overhand knots in the thread, and be sure they are tight.
