Tension problems I'm going insane!!! This is my sisters machine and I can't get the tension right. The top stitches are pretty good, but the stitches underneath are as jagged as a scerated knife. HELP!!! Oh, and she doesn't know where her manual is.

Start with the bottom- should allow thread to pass freely with slight tension when dangled from the thread. Tiny screw on the bobbin case turned clockwise tightens tension. Next, check upper tension. Thread should pull through with foot down, with good tension. Stitch should 'lock inside the fabric(use two pieces of fabric and make a seam, thread from both top and bottom should be visible when you open the seam.

Top stitch looks great, under stitch bunches. I have rethreaded, rebobbined, changed tension. same result. :(


Bunching of thread is 99% a top tension problem. Make sure you thread the top thread correctly. Thread the machine with the presser lever up. Test the tension by lowering the presser lever before threading the eye of the needle, by pulling the thread with your left hand and adjusting the tension with your right hand while slowly pulling downwards. There should be no resistance when the tension dial is on zero, and you should be able to feel more resistance when you increase the tension. Ideal tension is between 3 and 5. When your top tension is correct, your machine should operate correctly. If you feel no resistance with the presser foot down and the tension dial on 5, check the tension disks for fluff or broken thread. When you lift the presser foot, the tension disks should open and you would be able to remove any cotton or fluff. Good Luck

How do I adjust the bobbin tension? The stitches it produces are loose/loopy. The thread pulls out of the fabric like a basting stitch.


Make sure that your top threading is right. My sister in law has this same machine and it is a really hard thing to do, Your manual has very vague instructions but check your thread going through the tension discs by pulling on the top thread with the presser foot up, it should pull smoothly, now put the presser foot down, it should barely move. /Sometimes this seats the thread in the tension discs. She is having no luck with the buttonhole making. In 50 years of sewing I have never seen a more vague manual and no customer service at all.

The top stitch on my machine doesn't seem like it is correct. It seems like it isn't going deep enough into the fabric and hooking well w/ the bottom thread. It almost looks like one long stitch all the...


Hi. I think I know what you mean--the top thread looks like it's just laying across the fabric, right? This is because either the top tension is too tight or the bobbin tension is too loose. (Either condition will look the same.) Try it with a different color thread in the bobbin, you can easily see the bobbin thread cross the top thread on top of your fabric. Here's what to do:
  1. since you should hardly ever need to adjust the bobbin thread, we'll start with the top thread.
  2. Make sure you thread the machine with the pressure foot UP (opens the tension disks) but adjust the tension with the pressure foot DOWN (closes them so they will adjust). Use a size 12 or 14 needle and good-quality thread (it does make a huge difference!)
  3. With different color thread on top and in the bobbin, stitch an inch or so and check the stitch.
  4. Slightly loosen the top tension (move the dial so the numbers go lower). Don't move it a lot, just a little bit.
  5. Stitch again and check. Repeat this process, stitching, checking, and gradually adjusting the tension dial until you don't see any of the bobbin thread on the top (or very, very little) and don't see any of the top thread on the underside (or very, very little).
  6. IF this doesn't get the balance adjusted, then you'll have to play with the bobbin tension. (But generally, once this is set, you shouldn't have to mess with it again.)
  7. There is a tiny screw on the bobbin carrier that tightens or loosens a very small metal strip (where the thread exits the carrier). To tighten the bobbin tension, screw this just a tiny bit to the right. (Turn it to the right to loosen the screw, to the left to tighten it.) Again, just make a small adjustment each time and recheck your stitches.
Few things about sewing are more frustrating than stitches that aren't balanced!

Sure hope this helps!

re-thread the top, when the top looks good but the bottom is bad it is the top thread

Sears Kenmore sewing machine model number 15358 tension issues


#14 needle is way big for cotton napkin scrap. a #10 is good for most lightweight fabric. #14 is for sewing denim or levis, like that.

the tension problems on almost all machines regardless of price usually fall on the upper tension. the lower bobbin tension is factory set and it's rare you should ever need to mess with it.

if you have a drop in bobbin (top loading), tighten the adjustment screw all the way and then back it off 1/4 turn. if your machine uses a shuttle bobbin, tighten the adjustment screw all the way and then back it off in 1/4-turn increments until you can hold it in the air like a yo-yo and cause to bobbin case to fall slightly dipping your hand.

A dull needle and stitch length will also mess up your stitch. The idea is to narrow the problem down to one thing and one thing only -- UPPER THREAD TENSION.

So, if you have the right size needle for the job, with the right thread, and if your stitch length selection is correct (usually between 2 and 3 or 8-to-10 stitches per inch, the problem should be with your upper thread tension.

An easy way to fix this then is to remember: Loops on top, upper tension drop. Loops below, upper tension grow. If you get loops on top of your work, lower (drop) your upper thread tension to a lower number. If you get loops on the bottom, raise the upper thread tension.

Different stitches on the same machine will require different upper thread tension settings. Don't be afraid of it. Just remember the pneumonic: loops on top, tension drop, loops below, tension grow -- referring to upper thread tension.

have fun :)

it's the tension on the top thread.  rethread the machine and make sure the thread actually goes into the tension discs.  the thread should flow with resistance.  very good explanation of the problem by the way--good luck and enjoy sewing!
