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.
How do I stop my sewing machine from looping?
Looped stitches are usually caused by improper tension. If the loop is on the upper side, it may be corrected by loosening the top tension or by tightening the lower tension. If the loop is on the under side, it is usually best corrected by adjusting the upper tension.
How do I know if my bobbin tension is correct?
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.
How do you adjust thread tension?
Changing Bobbin Tension
Turning the screw a tiny bit counterclockwise will loosen the bobbin tension; turning it clockwise will tighten the tension. Some quilters keep two bobbin cases on hand, leaving one as-is from the factory and using the other when they need to make adjustments.
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 causes the bobbin thread to be loose?
Probable Causes: – Top or bobbin thread is not set correctly. – Thread does not match the needle. … – Hold down the bobbin with your right hand with the thread unwinding to the left, and hold the end of the thread with your left hand.
