Why is my Singer sewing machine not sewing correctly?
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.
Why is my sewing machine bunching up?
Your Thread Tension Is Too Tight
Sewing machine manufacturers suggest that you don’t mess with your bobbin thread tension too much, but you should adjust your upper thread tension if you keep getting bunched up thread underneath your fabric. If your tension is too tight, it can pull your thread and break it.
What should the tension be set on a Singer sewing machine?
The target figure should be around 30 to 40g. (1-1/4 to 1-1/2 oz) but it does not have to be too precise. However most people don’t have a spring balance handy, so alternatively you can tie a weight of the correct amount onto the thread and then jerk the bobbin gently upwards.
If the thread has knots, is not smooth, is uneven, or is loose on the bobbin, then it has not been threaded correctly. If your machine uses a bobbin case, follow your sewing machine’s instructions to remove the bobbin from the case and re-thread it.
