How do you fix the tension dial on a sewing machine?
What is the tension knob on a sewing machine for?
Sewing machine tension adjustment is controlled by devices that separately control the needle thread and the bobbin thread, putting varying amounts of tension (or strength) on the threads they control to form a strong, balanced stitch.
Why is my sewing machine so tight?
If the bobbin case falls several inches, the bobbin tension is too loose. If the bobbin doesn't fall at all, the bobbin tension is too tight. There is a small screw on the side of the bobbin. Using the screwdriver in your machine tool kit, turn the screw a quarter-turn right to tighten, left to loosen.
How do you know thread tension is correct?
Why is my thread loose on the bottom?
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.

What tightens or loosens the flow of the thread?
You've probably noticed the tension regulator on your sewing machine. It's usually a dial with the numbers 3, 4, and 5 highlighted or circled. This regulator tightens, or loosens, the tension discs that the thread passes down through before it goes up and through the looper.
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. What is this? If the bobbin case drops quickly the tension is too loose and you need to increase the tension.

Why did my needle bend?
Straight away you can see if the needle is rocking back and forth or is it laying perfectly flat! Check for a loose presser foot, or has the plate under the presser foot become loose. Pulling the fabric causes the needle to bend while the machine is stitching. A bent needle will hit the bobbin case and snap.
Why is my thread looping?
Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. Looping of stitches is sometimes caused by placing the bobbin in the bobbin case the wrong way.
What is normal thread tension?
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. This should be suitable for most fabrics.

Remedies: Check the threading order and thread correctly. Adjust the tension disc. Replace blunt or bent needles.
What does the presser foot do?
A presser foot is an attachment used with sewing machines to hold fabric flat as it is fed through the machine and stitched. A presser foot keeps the fabric flat so that it does not rise and fall with the needle and pucker as it is stitched.
Why is my fabric gathering when I sew?
Tension pucker is caused while sewing with too much tension, thereby causing a stretch in the thread. After sewing, the thread relaxes. As it attempts to recover its original length, it gathers up the seam, causing the pucker, which cannot be immediately seen; and may be noticeable at a later stage.
