Loops on the top of the fabric are usually caused by the bobbin thread not in the bobbin case tension correctly, remove the bobbin and reinstall it. You should feel a slight resistance when you pull on the bobbin thread.

My machine bunches tread on the bottom of the fabric when sewing. What am I doing wrong. This machine is new to me.

thread bunching under material is an indication that the needle thread is not at the correct tension
tighten up the tension setting until the result is where the both treads meet at the center of the materials being sewn
practice on pieces of scrap until you get it right

My sewing machine needle (very new one) keeps jamming every couple of turns of the needle - and the thread is very loose and loopy on the fabric. It makes a jarring noise

not quite sure how needle is jamming. I have had them break, had thread ball up underneath and caused needle to jam. Question is the needle in the right way, ie the flat side in as per manual, generally the flat side faces away from you. Sounds like your tension is not quite right if the thread is looping. Loops on bottom, bobbin tension, on top sewing machine tension

How do I fix the looping under the material when I sew?

the looping on the bottom usually is a tension problem, the top & bottom tension are unequal usually fixed by adjusting the top tension.
some people that I've talked with have had success with changing to a different size needle ( depends what type of thread is being used).
when the machine is threaded the foot needs to be up ( this releases tension on the thread), when the foot is lowered it the tension is set on the thread. if the material being sewed is too thick it raises the foot too high & releases tension on the thread ( the material has to be really thick to do this).
if there a piece of thread or lint in or around the tensioner or bobbin area it could cause trouble.
other wise if you've tried everything you can think of, take it back th the store & have them try it & tell you what is wrong.

also this machine has bad reviews (i'll provide a link so you can read them), people having the same problems as you are. the newer singers just don't seem to be the same quality tha the older ones were.
all bad reviews
mixed reviews

Feeder not moving

knotted up thread under the material indicates that the needle thread tension is incorrect ( needs tightening)
once you have that correct the material, will feed normally
use scrap when adjusting and the correct tension is when the top and bottom threads meet at the join ( middle -center )of the materials being sewn

How can I stop bobbin thread from jamming

This is usually caused by the needle not being threaded correctly or wrong size needle or wrong thread for the material or old thread, or incorrect tension for the material being sewn.

Trying to serge and my loops are to big.

Usually on a serger if loops too big you need to tighten top or bottom looper tension or both. The tighter the tension the smaller the loop. Also if you're not running the material straight with the knife it can make loops in places that although the same size as other loops it's covering less edge so the loops appear too large in places.

Cannot adjust my tensions. book is too vague...need help despratly!!!

Hi Karen:

Take a deep breath, count to 10... then slowly let it out. Ok. now. Most industrial machines are basic mechanical machines. Not much to go wrong with them. But they are so basic the manufacturers figure you would almost automatically know how to thread and adjust them.

There are a few things you can check.

I assume you got the needles when you got the machine. Did you know that some machines require left or right twist on the thread? Yes, I know... "Huh?" So first lets make sure your needle and thread match well.

Cut off a length of thread abotu 18 inches long. Take out your needle and thread the eye of the needle. Now hold one end of the thread up... does the needle slowly go down the thread? If it goes fast the eye is too big for the thread. If it slips and stops... the eye is too small for the thread. In either case you need different needles for this thread.

Next, In your instruction book... really study those pictures. Almost all machines require that the bobbin be inserted with the thread unspooling off the bobbin in a certain direction. Insert it wrong and it does strange things with tension and your loop.

Next... make sure you have threaded it correctly. This means lifting the presser foot lever while threading... make sure you are in between those tension discs. (I've had a machine that required that I wrap it 1.5 times around a tension disk... so make sure you are really studying those diagrams.)

Remember. Loops on bottom of material mean top tension is too loose. Loops on top of material means top tension is too tight and perhaps the bobbin tension needs adjusted (loosen top tension first!)

I hope you got the servo motor instead of the clutch motor.

Good luck

The loops formed on the back of the fabric are loose,how do i fix that?

You will need to adjust the thread tension. If the threads loops are on the "down" side of the fabric being sewn, you will need to increase the upper thread tension ( or in some very rare cases, loosen the bobbin case tension ) Refer to your owners manual for how to make this adjustment. As this adjustment is relatively generic for most home machines you may be able to refer to a manual for a different type or brand of machine.

When free motion quilting the bobbin thread loops and snarls. The machine is not currently on a frame, but I have a Grace Sturdy Light and want to put the machine in (the quilt is rolled and ready), but I...

Try threading the machine with the presser foot up and see if the loops and snarls go away.........

When the foot is down during the threading, the tension control is closed and the thread cannot enter as it should.

No tension control of the top thread and the bobbin thread cannot connect for a proper stitch.
