Why is my sewing machine looping 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.
Why is my sewing machine skipping stitches on stretch fabric?
The most common cause of a sewing machine skipping stitches is a problem with the sewing machine needle. The needle may be slightly bent, even if you can not see the bend. It may have developed a dull point from use, or it may have a nick in it.

How often are you going to lubricate a sewing machine?
Every four months is a good rule of thumb. You should also get your sewing machine professionally serviced every year or two to make sure it continues to run well. At your service appointment, your sewing machine will get oiled.
What number should tension be on 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 you fix bobbin tension?
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.
