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 is my Singer sewing machine looping underneath?
Thread looping on the underside of the fabric is always an indication that the upper thread is not correctly threaded. This happens when the upper thread is not correctly placed in the tension mechanism and has not been threaded through the take-up lever.
To tighten your bobbin tension, turn the tiny screw on the bobbin case a smidgen clockwise. To loosen bobbin tension, turn the screw counterclockwise. A quarter turn or less is a good place to start.

What should my thread tension be?
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.
Why is my straight stitch wavy?
When it’s just right, your stitch will look like the one in the middle. The one on the left is too tight, causing the fabric to pucker, while the one on the right is too loose, making the stitches loopy.
How does a sewing machine pick up bobbin thread?
With your right hand, turn the balance wheel toward you (counterclockwise) until the needle moves down and back up again to its highest position. The upper thread should have caught the lower thread in a loop. Pull the upper thread toward you and the lower thread will come up from the bobbin in a large loop.
