Decrease the thread tension by turning the dial
to a lower number. If the result is still not satisfactory,
then adjust the bobbin thread as explained below.

Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the
screw more than one full turn.
Remember to return the screw to its original setting before
starting your next project.

Upside down stitching


Am having a difficult time picturing this. Sounds like the upper thread is creating loops under the fabric and the bobbin thread is showing on the top of the fabric.

Make sure to use a brand new needle.

Remove the thread from the machine
ALWAYS raise the presser foot and rethread the upper thread.
Make sure the thread path is correct.

Check that the bobbin is turning the correct direction in the bobbin case and the bobbin thread is threaded through the bobbin tension correctly.

Set the upper tension to the midway point (factory standard), however, this setting may need to be tweaked for your particular machine.

Bring the bobbin to the top of the project Before beginning to stitch.
How and Why to Bring up the Bobbin Thread

Retest--begin sewing slowly.

If the upper thread is still showing on the other side of the fabric, the tension is too loose. If it is pulling the bobbin thread up to the top of the fabric, the upper tension is too tight

OR the bobbin thread tension is too loose. (CAUTION: make only small adjustments to bobbin tension--1/8 of a turn at a time!!! It also helps to mark the screw groove location with magic marker on the bobbin case BEFORE making any changes so you can back it out and return to the original setting.)

I have a Bernina 145 S activa and I can't get my satin stitch to work , it brings the bobbin thread to the top , what can I do ?


Do you use stabilizer when you are satin stitching? I had a teacher who also hooped the fabric with a spring-loaded embroidery hoop (turned upside-down under the presser foot so the fabric is flat against the needle plate) that would keep the fabric taut.

It is not uncommon for bobbin thread to rise to the top when doing embroidery, satin stitch, etc., especially if you are using lighter-weight thread than usual. You would normally loosen the upper tension so the upper thread will sink into the fabric. However, if loosened upper tension is not doing enough, you may need to adjust bobbin tension when doing embroidery, applique... You might try tightening the bobbin tension just a smidgen to get the bobbin thread to stay below the fabric. Be sure to mark the bobbin case before making any adjustments so you can return it to the original setting when finished with the satin stitch. (If you do a lot of satin stitch or applique, etc., you may want to invest in a separate bobbin case that is set up only for doing that kind of work--saves having to alter the bobbin tension frequently.)

The tension will not stay set . It sews great and then suddenly starts looping!! Like carpet!!and no bobbin shows through on back side at all help!!!


Ewww! Wondering if the tension mechanism has gone haywire.

First, change the needle. (Is the thread still in the correct path or has it "jumped" out of place? If so, try slowing down the machine.) Remove the thread. RAISE the presser foot to insure the thread seats properly in the tension disk and rethread from the beginning. Check that the bobbin is threaded properly. Check the tension setting and retest.

If it is still malfunctioning, it may need service.

How do I set bobbin tension?


Generally bobbin tension is the last thing to try to adjust on your machine. Most sewists adjust the bobbin tension ONLY if they are using very lightweight or very heavyweight thread in the bobbin. Most sewists will advise to make all possible adjustments to the top tension before tackling the bobbin tension to resolve issues.

Machine is 30+ yrs old and the tensions settings are ALL screwed up so it won't sew even tight stiches...need help setting all (3) tension dials...please help me!


Real Important: The objective is to even the top and bobbin tensions equally.
1. Remove bobbin case. Put bobbin in (rotating counterclockwise).
2. Put thread under the tension plate. Let the bobbin hang from finger and bob up and down lightly.
3. Adjust tension. The bobbin should extend one inch every time it is bobbed.
4. Put one drop of oil on race the bobbin case sets on top of. Replace the bobbin case and bobbin.
5. With the pressure foot up thread the top and give little tugs as you do this. There should be no snags or resistance. Make sure the thread goes in between the tension disc.
6. Now, put pressure foot down. Give a little tug to see if there is a resistance. Set the tension to four is a good start.
7. Try a piece of rag to sew. Set the tension on top to adjust for a perfect stitch.

You can find Singer bobbin winding instructions at http://www.singerco.com/resources/bobbin_wind.html.
"Birdnesting" occurs when there is no tension on the needle thread to pull the bobbin thread. This is easily corrected by rethreading the machine, following the threading path carefully and making sure the thread is fully engaged in the tension mechanism.

Cannot get tension balance correct


Try this. reomove thread and bobbin from machine.. Set thread tension to the middle number. Rethread machine carefully making sure the thread is thru the tension wheel. Replace bobbin making sure that thread is thru it's tensioner.
Rule of thumb. Loops on the bottom, problem is on the top. Loops on the top, problem is with the bobbin.

Tension problems


Hi bobbin....Because this machine is still unfamiliar to you, be certain that your upper thread is indeed completely threaded into and between the upper tension discs. Typically, raising the Presser Foot disengages applied tension upon the tension discs. It's quite possible that the lever which disengages your upper tension discs has slipped, and is no longer allowing the thread to freely position itself properly between discs. You may also firmly grasp the thread just before the discs, and firmly pulling with your other hand, thereby ensuring that the thread is completely within the discs. If those initial steps have not remedied your situation, examine your bobbin case, and ensure that the flat metal spring has not "cracked", paying particular attention the end where the thread exits the bobbin case under the spring. If the spring appears whole to you, using a screwdriver, in a counter-clockwise direction, turn the set-screw which fastens the spring to your bobbin case 1/5 rotation, and rethread. Set your upper tension to 4, and test sew using a straight stitch with medium stitch length. The knot after each stitch should appear to be in the center of your fabric. If the knot is still well below the center, loosen the bobbin case spring set screw by another 1/5 turn and repeat your test. If you must, you can repeat the process ONE more time, but no more. Remember, the set screw that secures the spring is very short, with little room for error. ****I recommend that you place a towel directly under the bobbin case prior to turning the screw, which will catch the screw and or spring for easy retrieval should you unintentionally dislodge them.....good luck my friend
