There could be several reasons why the thread is breaking. First thing, remove the top thread, install a brand new needle, ALWAYS RAISE the presser foot and rethread from the beginning. Sew slowly and pay attention to when, where, and how the thread breaks, ie does it stitch an inch or two, the top thread begins to stretch, and then it pops? Most likely, that's because the thread is hanging up somewhere, perhaps around the thread spool pin or a thread guide. Does the thread fray before it breaks?

SOURCE: CONSEW 206RB5 TOP THREAD NOT FORMING STITCHES AND BREAKING

you have your thread tension too tight that's why it is pulling the bottom stitch all the way through it looks good from the bottom but not good on top. Its pulled the stitch all the way through the material.
I had my own upholstery shop 18 yrs and tension gets you every time.Just loosen the top tension.

Hi, when your thread breaks or frays right before in goes through the eye of the needle:

  1. Change your needle - after awhile, the eye can wear down and cause your thread to break or fray, eventhough it looks like the thread isn't even going through the needle. When you change your needle, make sure to install a needle that is compatible with the thread you are using (see below).
  2. If your thread still frays or breaks, make sure you've threaded your machine correctly. Most machines have a hook or bar right above the needle that your thread need to pass thru before you put the thread thru the eye of your needle. Sometimes that spot above the needle is really hard to get to, and sometimes the thread slips out. Always a good idea to double check. If you are still having problems, the needle you are using is probably the wrong size.
There are lots of needles on the market, and lots of threads. You need to make sure your needle is compatible with the thread you use for each project.

The most common needles are size 80 and 90 universal needles, which are fine for most sewing projects. But if you are using a specialty thread, you need to use a needle that is designed to work with that particular thread. For example, top stitching needles have a larger eye than a universal needle, because top stitching thread is thicker than sewing thread. The same is true for metallic thread - needles made for metallic thread an eye designed to allow the thread to pass thru without fraying. Further, if you using fine thread, you need a small needle.

FYI - unfortunately, thread sizes do not correspond directly with needle sizes. Small needle numbers indicate a needle with a small eye. But the smaller the thread size, the larger the thread. For example, size 50 thread is very fine and would usually be used with a size 70 needle. Size 30 thread is fairly thick and would probably be used with a size 90 top stitch needle.

Hope this helps, and remember, you should always change your needle after about 10 hours of sewing, no matter what size needle you are using. If you have more questions, please post again. Thanks, Ginny

SOURCE: My lowerlooper thread keeps breaking. I can only

The lowerloop thread kept getting cut by the upperlooper.....I rethreaded the machine in order and then made sure that the lowerlooper thread was UNDER the part of the machine that makes the looks the loopings (silver part that comes to a point on the right side of the needles...sorry I don't know what to call it) and the upperloop was ON TOP of the same part.....it started working great. I actually have very nice tight stitches now.

This sounds like a backwards needle. Take out the needle and when you re-insert it back in, make sure that put the flat side to the back.

The tension my machine seems wrong. When I sew the stitching at the bottom of the material is right but the sewing on the top seems loose.


Tighten the top tension. However, if the bobbin thread is actually pulling up on the top of the fabric, the bobbin tension is too loose. Both top and bobbin threads should pull enough against each other that they meet in the middle of the fabric without causing puckering.

Another thing to remember. ALWAYS RAISE the presser foot when threading the top thread!

How do I adjust the bottom thread tension on the 2 needle cover stitch?


Go back to the tension adjustments that were doing well with other fabrics.
You may need to go to a smaller size needle, and a finer thread. Sometimes I use a wooly nylon in my looper because it is very stretchy, but be careful when you pull it through as you are threading it because it will also break easily if you don't have your tensions full open as you are pulling it through.
Start out by buying a sheet or roll of Solvy. You can either cut it into strips to lay on top of the material as you sew or under it if you prefer. It should make the material lay flat as it sews. I have used tissue paper before under it to make it lay flat and keep it flat to make the looper thread stretch itself out as it sews.
If your looper thread tension was too tight on other fabrics too, that is a whole other problem.

whether its bias or straight does not matter to machine. loosen the bobbin tension and put more tension on take up spring by inserting a screwdriver in the slot of the top thread tensioner. turn to right.

The bottom stitch is very loose. I've tried tightening and loosening the screw and the problem remains...HELP!


The bottom stitch is affected by the TOP thread tension :) First go back and make sure your bobbin tension is correct since you adjusted it. It should drop slightly when held suspended by danging it by the thread. If it reels out to the floor it is too loose. If it doesn't drop at all it is too tight.

Now that you have that adjusted look at your top tension. If it is loopy on the bottom side of the stitch the TOP tension is too loose. Increase the top tension.

Now take some scrap material and set machine to a wide zig zag, medium length stitch and sew a bit. Compare the top and the bottom sides of the stitch. They should look identical. Remember the TOP side effects the bottom and the BOTTOM tension effects the top side. Adjust accordingly until they look identical with no loose threads or loops and no puckering (puckering means it's too tight).

I keep having problems with the stitching on my machine. 1) when you sew the stitches looks normal from the top but when you turn the material over it looks like one big tangled mess. 2)When it does...


It is usually in your top threading, make sure that your thread match in bobbin and top threads. Mixing sometimes causes a problem. Also make sure that nothing is tangled. Also, check your needle and put a new one in just to be sure, then check your manual for size of needle and what kind of project you are doing. Hope this helps.

Singer 221-1 stitching is good on bottom but not on top


pucker is caused by too loose or, to tight adjustment of: the thread tensioners both the bobbin tensioner and, the needle tensioner need to be adjusted: to adjust the needle tensioner turn the side knob clockwise is tighter counterclockwise loosens; the bobbin tensioner is a tiny screw on the bobbin holder adjust both tensioners until your stich loops' both top and, bottom are tight but, the machine does not break the thread
