Tension When I try to run a straight stitch, I have a ton of thread on the bottom of the fabric. Any ideas? I have a Janome Model DC 3018 and whenever I try to sew with it the stitching gets messed up. The stitches on the top of the fabric are fine but the stitches on the bottom are tangles masses. I have changed the needle, threaded and rethreaded (with the presser foot up), rewound the bobbin, changed the thread and started all over and have tried changing the tension settings. Nothing has made a difference. What is happening?? Thanks....

    I dont know what happened but i was using my machine, Model 8763, for the first time and was just testing the different stiches and i started to sew a small blanket for my daughters doll and half way thru it just beeped 4 times and stopped, i tried again and it did a couple stiches then 4 beeps and stopped, the stitches on top looked fine but the bottom was all bunching. I read over and over that if that happens then to rethread the top, I have rethreaded it several times and had my mom, who is a seamstress look at it and rethread it and it still does it, any ideas what else I can try? I have also tried changing the needle and changing the tention on the top thread.

Check your tension disks, with your presser foot up, and the tension dial on zero. Sometimes a piece of cotton breaks off between the tension disks and then prevents the disks to work properly. Also make sure when you thread the machine, the thread does go through the disks and over the take up lever. After you threaded the machine, before putting the thread through the eye of the needle, lower the presser foot and while pulling on the thread with your left hand, increase the tension with your right hand. Do it slowly and you should feel in difference in tension. If this is the case, your machine should work fine.

The zig zag stitch on my Janome MC 3000 skips stitches all other stitches work fine. Any solutions?

Be sure stitch is in between the two fabrics when straight stitch. Adjust tension until stitch is between top and bottom fabric. Use different color top thread to make it easier to see. Once tension is correct sewing straight, switch to zigzag.

Remove hook race and bobbin. Clean area with vacuum.
Replace needle.
Try different thread and fabric.

Why is my stitch distorted

Top thread is "frayed"?

Could be tension is too high, problem with needle, needle wrong type, other.

Does it straight stitch ok using same fabric, thread, needle, bobbin, and tesnsion?

Having issues with my Janome 6500P with stitches since I had service

Sounds like a threading issue.
Be sure to install a brand new needle (every 8-16 hours!).
Remove the top thread completely from the machine.
ALWAYS RAISE the presser foot and rethread from the beginning. You may need to tweak the top tension until the two threads meet in the middle of the fabric.

This should take care of your problem. If not, you may have the technician look at it again.

Remember, thread problems under the fabric are usually top thread issues. Thread problems appearing on top of the fabric are usually a bobbin thread issue (or top thread tension being too loose).


How can I get my janome 11000 to work when embroidering? The bottom thread doesn't even show and top thread is always breaking.

The tension(s) may be too tight and could be threaded incorrectly. Start out with a brand new needle. Be sure to RAISE the presser foot when threading the upper thread. Consult the owner's manual to be sure it is threaded in the proper order. Test your stitch on a straight stitch and adjust it so both threads meet in the middle of the fabric. This setting works for straight stitch. However, usually the upper thread tension is loosened a bit for embroidery so the bottom thread will not show on the top of the fabric. Test it on some small embroidery patterns first until it's where you want it.

Model 525B. Why is bottom stitch loopy and the hand wheel and needle jam?

try a new needle

try adjusting the top thread tension to see if that helps the bottom loopy stitch

Why isbobbin stitch on top weird how do i fix

If the bobbin thread is pulling through to the top of your fabric, your needle thread tension is too tight. Loosen the top tension until the needle and bobbin threads meet in the middle of the fabric.

My Janome memory craft 4800 embroidery stitches are appearing on the bottom of fabric rather than the top. can anyone help?

Try to tighten the top thread tension. Make sure the thread is going through the tension disc.

I have a singer 7258 that I can not get the tension to loosen up on. The top stitch is straight across and adjusting dial doesn't help.


Adjust the tension

Load your sewing machine with one color on top, threaded through the needle. Load the second color thread into the bobbin and thread.

Fold the scrap fabric in half, and sew a straight stitch at least 2 inches long. Look closely at the seam. If you see loops of the bottom color thread on top of the fabric, proceed to Step 3. If you see loops of the top color thread on the bottom of the fabric, proceed to step 4.

Loosen the top tension. Since the top tension is so tight, it is pulling the bottom thread up through the fabric. Loosen the top tension by turning the numbered knob on the front of the sewing machine counterclockwise by one number.

Tighten the top tension. Since the top tension is too loose, the bottom thread is pulling the top thread down through the fabric. Tighten the top tension by turning the numbered knob on the front of the sewing machine clockwise by one number.

Sew a straight stitch 3 inches in length. Check the stitching. It is perfect if the threads meet in the middle, and you can only see the top thread on top and the bottom thread on bottom. If it still needs adjusting, go back to step 2 to repeat the needed steps.

Using two different colored threads makes it easier for you to see which thread is being pulled.

Always use proper precautions when working with electrical machines.


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 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 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.
