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.
Why is my sewing machine sewing gathers?
When the tension is set too high, the thread is stretched when sewing, then relaxed afterwards. Sewn with longer seams when stretched, the thread gathers the fabric, leading to a puckered seam. … A high tension may stretch the thread when sewing and cause seam puckering afterwards.
Why is my thread bunching up?
What should I do if I experience thread bunching? As “thread bunching” occurs on the underside of the fabric, some people think it is due to the lower thread. They check whether the bobbin is sitting correctly in the bobbin case or even replace the bobbin. … On many models, the upper thread tension is set automatically.
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 does my sewing machine keep bird nesting?
Bird nests occur when thread bunches up underneath the needle plate, causing broken threads, skipped stitches, or uneven tension. This is typically caused by the top thread not being threaded correctly or a sewing machine tension issue.
Why is the tension wrong on my sewing machine?
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.

How do you solve a stitch?
Slowing down, breathing deeply, stretching, and pushing on the muscles may help. Avoiding large meals before exercising, limiting sugary drinks, using good posture, and slowly building up your strength may help prevent a side stitch from happening in the first place.
What number should the tension be on a 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.
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.
Threads can get bunched up at the beginning of sewing if the top and bobbin threads have not been properly placed underneath the presser foot before starting to sew. Ensure that both threads are under the presser foot and placed toward the back of the machine before lowering the presser foot to start sewing.
First, your needle may be dull or damaged and needs to be replaced. You should also check that you are using the correct needle for the type of fabric you are sewing. … If the needle is not inserted correctly, it will not be able to pull up the bobbin thread and will cause skipped stitches.
