Why is my sewing machine looping?
Causes of Stitches Looping

What causes uneven stitches on sewing machine?
The most common reason for uneven stitches is old or inferior thread. Another cause for uneven stitches is the fabric is being pulled while sewing. When sewing it is important to remember to never pull the fabric – allow the fabric to be taken up by the sewing machine.
Why is my thread looping 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.
Why does my top stitch look wrong?
Poor thread tension on a machine-sewn seam can result in an unstable seam, puckering, or just plain unattractive stitching. Perfect machine stitches interlock smoothly and look the same on both sides of the fabric. If you see small loops on the right or wrong side, the thread tension isn’t correct.
What is the best stitch length for machine quilting?
For straight stitching, it is advised to set your machine’s stitch length to 2.5 to 3.0 or about 8-12 stitches per inch. This range works quite well for a majority of machine quilting but there are always exceptions when you make a rule. For threads with sparkle or shine, use a longer stitch length.
Why are my stitches different sizes?
When the bobbin case is threaded wrong, the upper thread and the lower one do not work in sync, forming uneven stitch or uneven feed among layers of fabric. Check the bobbin case and re-thread if needed. The thread should pass through the thread side slot in the case before being brought up to the needle.
