Tip & How-To about Sewing Machines

How to fix looping on the bottom of fabric.

This is usually caused by lack of top tension or threading the machine with the pressure foot down.

-Set the top tension dial to 5
-Raise the pressure before threading the machine
-"floss" the thread by holding the thread as it comes off the spool with your right hand and holding the thread right before the needle with your left hand. Make sure to do that with the pressure foot up. What happens is sometimes the thread doesn't go into the tension discs all the way due to lint or something else.

With the pressure foot up, you should be able to pull the thread easily right before the eye of the needle and when you put the foot down you should then feel a fair bit of tension on the top thread.

Having trouble with the tension. Not sure if the top thread is done right. There are large loops on the bottom when I try to sew. The thread breaks after 15 or so stitches. I did put in a new needle, but it did not help.


looping on the underside is symptom of insufficient tension on top thread. so check the top threading path again, raise pressure foot first as this opens up tension discs. make sure thread is seated into tension device correctly and then lower pressure foot and pull downwards on the thread. is it hard to pull? is tension set on middle range? 4 or 5 usually. if its not firm and you have it set right then dial is faulty.

sewing two pieces of cotton fabric with batting between. using NEW clark brand thread, NEW size 14 needle, during sewing the thread on the underside of the piece knots up jams the machine after sewing about 1". Using a singer model 626. tension set on 2 then changed to 1. I have rewound the bobbin, changed the needle, unsure what to try now?


Threads underneath is the top thread coming down and not being tensioned enough by the top tension dial. So turn the top tension back to 5 and test sew. Does this produce an even stitch tension top and bottom.

If this then is still giving the looping underneath, recheck that the top thread has seated into the tension discs fully, always raise the pressure foot before threading the top of the machine so the tension discs are open fully.

Also cleaning top tension discs sometimes helps, to do this, turn tension dial right down to zero, raise pressure foot, remove all top thread and "floss" between the tension discs with the selvage edge of a clean piece of cotton fabric, if you get lots of gunk on the fabric edge from the tension discs, then keep cleaning with a fresh bit of fabric. Thread, especially, black or cheap brands, will shed dye particles and this will build up in the tension device with time. You can also clean with some denatured alcohol, just wet the fabric edge and floss again. Just don't get onto any plastic bits.

Now thread up again, set tension to 5 and check that the top thread is in tension by threading down to just before the needle, lowering the pressure foot, and pulling on the thread. It should be firm. If you can't get this to happen at all, then the tension device may have broken and will need to be serviced by a technician.

Also if you don't have a manual for your singer you can download at http://www.singerco.com/accessories/instruction-manuals, just type in your model number and click search.

The top stitch is perfect but underneath the material there are many loops. I am assuming this is from the bobbin. How do I correct this?


no, more likely your top tension is too loose causing the loops on the underside of your fabric, loops on top would be bobbin too loose. raise presser foot and rethread top thdead pulling thread into tension fully. set top tension dial to 5 and test sew. if still looping underneath try tightening top tension by turning dial up to 6. but usually top tension should only need minor adjustment tweeks. you can test top tension by lowering pressure foot to engage tension and holding thread just above needle thread guide, pulling thread downwards . there should be resistence on it to your pull. if you cant feel any then tension device may be faulty, and require service.

thread is botching up on the bottom. kenmore 17828490


Check the top tension dial is set to the middle setting of 5 or so and also check if the thread is actually between the tension discs and under tension. Lower the pressure foot, then pull the top thread just before it gets to the needle, it should be very firm. If not, then raise the pressure foot, pull the thread out and rethread the top thread, pulling it firmly between the tension discs.

Loops on the underside is usually top tension issues and visa versa if you get loops on top, check the bobbin thread tension.

I was sewing and all of the sudden, the bottom thread became tangled . I have tried to rethread and clean the bobbin scuttle area. Nothing works.
