How do I fix the upper tension on my sewing machine?

To decrease your top tension (if your top tension is tight) turn your knob so that the numbers are decreasing. Try 1/2 to one number lower, then test on a light piece of scrap fabric with a different colour thread top and bottom.

How do you fix upper thread tension?

If the tension isn’t perfect, fix it by adjusting the bobbin spring; tighter if the bobbin thread shows on the upper layer, and looser if the needle thread shows on the underlayer. Make another test seam, and examine the stitches, repeating until the stitch is balanced.

How do you adjust the tension on a sewing machine?

No matter what the problem, start by adjusting the top (needle) tension:

  1. If you’ve determined that more tension (strength) is required for the needle thread, turn the tension knob (or digital setting) up just a bit (refer to your manual).
  2. If the bobbin needs a little more pull, lower the needle thread’s tension setting.

What number should the tension be on a sewing machine?

As the bobbin thread tension is factory-set and wouldn’t usually be adjusted for normal sewing. So we’ll be talking only about the top thread tension since that’s where you’d usually make the adjustments. The dial settings run from 0 to 9, so 4.5 is generally the ‘default’ position for normal straight-stitch sewing.

Why is my thread bunching up 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.

How do you fix bobbin tension?

To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.

What width should my sewing machine be on?

A straight stitch has no width so it makes sense to set the dial at “0”. However, each machine varies so you will want to set the Stitch Width dial at the position where the needle is centered over the stitch plate. This will give you the most accurate seam allowance.

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).
