If the machine is threaded wrong, not only does it make the thread breaks easier, but is also more likely to create loose stitches. Check the threading to see if the thread has passed through the entire thread guides, the take-up lever and the eye of the needle.

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.

How do I stop my stitches from unraveling?
To prevent those points from unraveling and stretching out of shape, you need to secure them with a back stitch or lock stitch. Backstitching is done by sewing backward and forward at the beginning and end of a seam, on top of the seam stitches, to prevent the stitching from coming undone.
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.
Why is my thread bunching 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 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 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.

- Next, insert your threaded needle inside the loop of the snag and pull through until the end of the thread is close to the loop. …

What happens if a stitch comes undone?
When a suture comes undone, this is called wound dehiscence. This occurs when the wound opens up along the suture and is the most common complication of a wound. Ideally, the sutures will stay in place until new tissue forms and helps the wound to heal.
Why is my bobbin tension so loose?
Needles, threads, and fabrics: Different thread sizes and types on top and in the bobbin can throw off basic tension settings. A needle that’s too large or small for the thread can also unbalance your stitches, because the size of the hole adds to or reduces the total top tension.
Can you reverse stitch with a walking foot?
No, you cannot sew a reverse stitch with a walking foot. This is because the foot is not designed for sewing in reverse. When you sew a walking foot in reverse, the machine feed dog moves the fabric backward, and the top feed dog of the walking foot moves it forward.
