    I am having this problem as well on lightweight cotton. I cleaned the machine and kept dialing the tension down a little at a time until I got to 0!! And I still have the loops on the surface. I really don't know what to try next. Any help?

Your upper tension should be set on 4, and make sure it is threaded properly, the thread is between the didc'c uf upper tension.

Top thread keeps breaking


Don't ship it back and the problem is not the tension settings. Even on the tightest setting the thread should not break. Most likely the machine is not threaded correctly. Possibly, you are using too thick a thread or a needle that is too small.

Solution back to basics:
1. verify that you are not using upholstery thread. Use a standard cotton poly mix.
2. the bobbin thread should be the same as the top thread.
3. consider watching a video showing the machine being threaded and make sure the needle is in the top position.
4. sew a test pattern on a normal weight fabric like an undershirt - avoid very thick material.

If this solves your problem then change one item at a time. Use a heaver thread if that is what you want. If it works ok then go to a thicker material, etc. Do not change two or more things at a time..If you have a problem it makes it hard to identify the source.

I am having issues with threading my machine. I have followed the instructions but every time I sew on the machine the thread on the top sews correctly but underneath the cotton gathers up. What am I doing...


If the thread is bunching under the material it is the top tension. While threading the machine be sure the foot is in the up position until you are done threading it. If you have tried that and it still bunches you need to tighten the tension a bit at a time until it starts sewing correctly. Be sure you are starting with a clean machine and that the thread is not too large for the needle ....


hope this helps.

The cotton on my bernina 801 keeps jamming


Loops on bottom indicate a top thread tension problem.

Make sure needle is the correct size and not bent or broken
Make sure it is threaded properly with the lever UP.

Do a test stitch.

If it still loops below... tighten the top tension and do another test stitch... keep doing this until the stitch is balanced.

BTW... always grasp and hold both threads when starting a seam.

I am sewing a cotton piece of fabric for a dress and i do not know how to set the tension for cotton


The tension for cotton is set the same way tension is set for any fabric:

1. The thread should pull freely with a small resistance before/after it goes through the needle, on many machines that's half way on the tension adjustment.

2. The bobbin thread when dangled by the thread with the bobbin inside the case should drop down a bit when slightly flicking your wrist like you do with a yo-yo. If it reels out to the floor the tension is too loose. If it doesn't drop at all it is too tight.

3. Now make sure you use the right type of needle. For cotton you want a "sharp" and for reg. weight cotton about a size 10 maybe 12.

Now take a piece of strap cotton material like you're going to sew a seem and sew with a wide zig zag. Example the top side and then the bottom. They should appear identical, flat with needle holes at each side where the thread disappears to the other side. You should see no loop where the threads over lap each other and the material should not be puckering in the middle.

If that is not what you see then think this way:

The TOP side of the stitch is effected by the BOTTOM thread. the bobbin tension.
The BOTTOM side of the stitch is effected by the TOP /needle tension.

Adjust the responding tensions until the stitch looks the same on both sides. Now you are ready to sew your cotton! :)

I'm having trouble gathering fabric...no matter how I adjust the stitch length it seems to be too tight and I break the threads when I try to gather. Help!


So you are sewing two rows of straight stitch at 10mm and 20mm from fabric edge with a stitch length of 4? Are you using good quality thread? I like Molynecke, Guttermann or Sylko Supreme.

Try loosening the top and bottom tension too, and use a gathering foot if you have one.

A quick solution is to zig-zag over a length of pearl cotton or similar heavy weight string/thread, this works well for large volumes of gathers such as around a bed valance frill.

For large volume gathering like cushions and bed frills, I use a pleater/ruffler attachment, however, this has only 3 settings so isn't a variable gathering effect.

I have a ramie, cotton, poly, spandex blend of material. It is pretty stretchy. I can't find the right tension combination on my Necchi royal series machine. How do I know if it ist the machine or the...


I would try using some tear away stabilizer under your material and stretching as I sew . If, you do not have interfacing try using some good old fashioned gift tissue paper. Make sure that you are using good thread, Sulky or Guterman, cheap thread is terribly linty and causes build up in your machine.

Gobbs of thread gather on backside of material, while front stitch is good...how do I correct this


Hi! Here are two things to check that generally cause problems like this:

1. Check that you're threading the machine correctly, especially the take-up lever.

2. It may be that you need to tighten the top tension. When the top tension is too loose, it'll cause big gobs of thread, like you say, on the back of the material. All this thread is actually top thread (not bobbin thread). (I recommend using different colored threads in your top thread and in your bobbin when you suspect tension problems.)

A couple of things to remember when you are adjusting the tension:
  • Always adjust the tension with the pressure foot DOWN.
  • Thread the machine with the pressure foot UP (so the thread can slip easily into the tension disks).
  • The higher the number on the dial, the tighter the tension.
  • Adjust in small increments. Stitch a few inches, check, adjust, stitch, check adjust--and repeat as needed.
I'm in the process of posting some photos about tension adjustments on www.robbiesews.blogspot.com. Check there later tonight and I should have them up.

Let me know if this helps, ok?

The material gathers when i sew


Rethread the machine from the spool to the needle.All machines thread the same. TTN tension, take up, needle.
Beginning with the spool, guide the thread through the thread guides to the tension assembly. Pull the thread through the tension assembly and test it to make sure the tension is working correctly.
(To do this test, adjust your tension setting to normal or medium or 5 or something in the middle. Raise the presser foot and pull the thread through the tension. It should pull easily!! Lower the presser foot and pull the thread. It should pull noticeably harder.) If it passes this test, continue up through the take up lever,then down through the thread guides to the needle. Make sure your needle is fully inserted and turned the correct way.
You need to be sure your tension is working correctly. Adjust the tension to 9 and pull the thread. It should be hard to pull. adjust the tension to 2 and it should pull much easier. If it works as described, then adjust the tension to 4 and your stitch length to 2.5 and try it on some medium weight fabric.
If you are sewing on light weight fabric set your stitch length to 1.5 or 2. You may even have to reduce the tension to less than 4. You can reduce the tension until you see loops on the bottom of the fabric at which point you should tighten the tension to remove the loops.
