How do I adjust the tension on my top thread?
Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension. Some quilters keep two bobbin cases on hand, leaving one as-is from the factory and using the other when they need to make adjustments.
What tension should my sewing machine be on?
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.
Why is my sewing machine looping 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 top stitch loose?
Another reason you may experience loose stitches is that the thread tension may be low and may not be tight enough to hold these threads tighter to the fabric. When you experience loose thread, you should readjust your tension to see if it is close enough to stop the loose stitches.
What should the tension be on a Brother sewing machine?
The standard tension setting is 4. Start with this, and based on what your test stitching looks like, tighten the tension (below 4) or loosen it (above 4). Typically on Brother machines, to loosen the upper thread tension, turn the dial left. To tighten it, turn the dial right (source).
What tension should Jeans be set at?
Tension is ideal up to 6, but is too high after that and pulls the top stitch into a flat line. Regular thread, bobbin thread view. The bobbin stitches clear up around 6 but don’t improve much after that.
How do I know if my bobbin tension is correct?
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 causes bobbin thread to bunch up?
Bobbin Thread Tangling
The bobbin keeps pulling and jamming collecting a lot of thread beneath your fabric. There are several culprits for this ranging from a dull needle, improper threading or tension. The tension in both your upper and bobbin threads need to be even. The bobbin could also be placed incorrectly.
Why is my bottom stitch not straight?
If your thread is pulled tight on the underside and not forming an even stitch then (counter-intuitively) it’s usually the top thread tension that’s wrong. Sometimes very lightweight fabrics such as sheers can get dragged down into the machine so it’s a good idea to use a straight stitch plate.
