Hi. Loops on the underside of the fabric are generally caused by the upper tension being too loose. Use a size 12 needle, and size 50 thread with different colors in the upper thread and in the bobbin. Sew an inch or so, look at the stitch and adjust, tightening the tension just a bit at a time.

There's more detail in the tip I wrote about adjusting tension.

Hope this helps!

Your tension is way too loose on top or too tight on the bobbin. Try adjusting the top tension one number at a time until you get it right. (Only adjust the bobbin tension as a last resort). Also you could have different thickness of thread in the bobbin than on the top or are sewing a very heavy fabric. Try adjusting the tension with same thread in both bobbin and top and use a normal weight fabric until you find the right tension to get you back to a normal stitch before going to a heavier fabric or thread.

The stitches on the underside are looping I’ve retreaded both the needle and bobbin and neither makes a difference


You are getting a thread mess under the fabric? Frequently, this occurs because the top thread is not fully seated in the tension disk.

Install a brand new needle.
Remove the top thread from the machine.
ALWAYS RAISE the presser foot and rethread the machine from the beginning.
If necessary, adjust the top tension so the top and bobbin threads meet in the middle of the fabric.

Top stitch is fine bottom is loose. Have tried adjusting tension but not working. If I get tension too tight breaks thread so I gradually change tension to no avail. Please help


Check your stitch sample. The loose stitches under the fabric--are they actually top thread???? Usually,stitch problems under the fabric is a result of a top thread problem. In this case, it could be bird nesting.

Tension issues on my singer quantum 9960


A #16 needle seems pretty big for FMQ. Are you also getting pin holes in the fabric? Try using a top stitch, embroidery, or metallix needle.

Eyelashing is often a result of moving the fabric too quickly. Try speeding up your sewing speed or slow down the fabric movement. The object is to get the stitch speed equal to the fabric movement--and keeping it consistent. I tend to make swirls too fast which causes eyelashing.

It could also be tension. Be sure to ALWAYS RAISE the presser foot when threading the top thread.

Remove the thread from the machine.

ALWAYS raise the presser foot when threading the upper thread. This releases the tension disk so the thread will seat properly. Be sure to use a brand new needle and that it is the correct type needle for the project, thread, and fabric.
All About Needles
Verify that the thread path is correct. Check that the bobbin is inserted correctly and threaded through the tension on the bobbin case properly. AVOID old or bargain bin thread. You may even try a different brand of thread (some machines and threads are just incompatible.)

Back side of stitches are loose


increase the thread tension of the needle thread
this is an indication that the tension is not enough to pull the bobbin thread up tight

Needle stitch fine. Bobbin stitch loops.


First, try a brand new needle.

Second, consider using a better quality thread. By all means, AVOID old or bargain bin threads. Coats & Clark used to be a standard, but thread quality has improved over the past few years, so you may want to check out other brands like Aurafil, Superior, Isacord, etc. Also, cotton wrapped polyester thread releases thread lint that contributes to build-up of gunk in the machine. Some sewists have noted that they experience more sewing issues when using C&C threads. However, some machines will do better with certain thread brands than others, so some experimentation may be beneficial.

Third, check the stitch on your sample again. Generally, when thread loops appear on the underside of the fabric, it is the upper thread that is the problem. If loopy threads appear on the top of the fabric, it is the bobbin thread that is the issue. You can even use a different color in the top to help distinguish which thread is the problem.

Fourth, when threading the upper thread, Always Raise the Presser Foot during the threading process so the tension disk is released and the thread can seat properly. "Bird nesting" occurs when the thread is not seated in the tension disk.

Fifth, when the upper thread appears on the underside of the fabric, the upper thread tension is too loose. If the bobbin thread appears on the top of the fabric, the tension thread is too tight (or the bobbin thread is loose). Start out with the upper tension set at the midway point and tweak it from that point. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric.

Also, remember that tension is not static--a tension setting for chiffon will most likely not work on cotton or denim. Get comfortable adjusting the tension to suit the project you are sewing.

I can't seem to get my tension right. It keeps skipping and putting loops on the under side of fabric and the thread keeps unraveling and breaking . Tacsew T111-155


Check the needle to be sure it is the correct size for the type of fabric you are sewing and does not have a burr on the tip.

Raise the presser foot when threading the machine and this will open the tension control so the thread can properly seat into the control and form a proper stitch.

When the machine is threaded with the presser foot down, the tension control closes and the thread cannot enter as it should. In this case, the bobbin thread is the only thread with tension.

If it was sewing correctly BEFORE the needle break...why did the needle break in the first place?...and what fixes did you make?
If it sewed properly...what changed?

Cut your upper thread close to the spool...make sure the presser foot is raised and pull the cut off thread section through/out of the machine from the needle area (sewing direction...do not pull the thread backwards!)

Clean out the bobbin area...remove any traces of lint or pieces of thread...look for any broken off needle pieces... brush the bobbin area out....then add a drop of sewing machine oil (but only if your manual says to oil that area).

Remove the needle plate to expose the feed dogs...brush/clean out that area too and add a drop of sewing machine oil...then secure the needle plate back on.
Replace the needle...do it again...yup...some needles arrive bad from the factory. Make sure the needle is inserted and positioned properly. Then thread the machine WITH the presser foot in raised position. (The thread needs to get seated into the upper tensions.)
..with the.presser foot down...thread the new needle.
Oh...and use the correct needle for the thread. (a universal 80/12 is standard).
Thread can cause issues too. Try a different bobbin, or maybe a different spool of thread to see if that makes a difference.
