Your Thread Tails Are Too Short If the thread tails that come out of your bobbin are shorter than two inches, they may get sucked into your sewing machine when you begin to sew. This can cause thread bunching underneath your fabric.

Why does my thread bunch up 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.
How do I fix bobbin thread bunching?
How to Fix Bobbin Thread Bunching and Other Threading Problems
- Thread the Machine Properly. Re-thread the upper part of the sewing machine making sure the thread is passing through every single thread guide on its way to the needle.
- Change the Needle.
- Inspect the Bobbin.
- Clean the Machine.
Why does my sewing machine keep knotting underneath?
If your sewing machine thread is not properly threaded, the bobbin thread won’t be pulled up into the fabric the way it needs to be. Occasionally the upper thread can catch on a moving part or get stuck, which impedes the easy flow of thread through the needle, creating a tangle.
How do you tell if your bobbin tension is off?
Swiftly pull up on the thread. 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 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.
Why is my thread Birdnesting?
The main source of birdnesting or looping is improperly inserted or threaded bobbin or running the embroidery machine with no bobbin. Although operating your system without a bobbin is not strictly birdnesting, it can cause similar problems.
What should bobbin tension be?
Proper bobbin tension is essential to good embroidery. If tension is too tight, unwanted bobbin thread may begin to show on top of your garment and you may begin to experience frequent thread breaks which wastes time and money. Bobbin tensions should be 18 to 22 grams (up to 25 grams when embroidering caps).
What is the best stitch length for sewing a straight stitch?
approximately 2-2.5mm
Set the machine for straight stitch, with a stitch length of approximately 2-2.5mm. Sew, just inside the seam allowance.
Why is my fabric bunching up when I sew?
Cause. 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.
What does a properly balanced stitch look like?
Forming A Straight Stitch
To easily test the balance of a straight stitch, use contrasting colors of thread in the needle and the bobbin. The stitch is balanced when you cannot see two colors of thread on the fabric.
What tension should I use for cotton?
Cotton requires a moderate tension setting, usually between three and four. Always start adjusting your tension settings with your upper tension.
