Most likely, the needle is not inserted correctly. You don't say what kind of machne you are using, but every one has a different needle insertion. . Some thread front to back, some left to right, and some have an indentation just above the threadhole.. Also, if the needle is not perfectly lined up, it won't thread, or sometimnes, if the bobbin is not inserted correctly, it won't thread.Check your threading diagram, and pay close attention to the needle position.Good luck!

You may have the tension set too tight or are not using the correct needle. Or, the bobbin thread may not be the same as the top thread. Also, here is a little trick. Put a piece of typing paper under the edge of the material and sew across the paper onto the material on all edges that you sew off of, to give a little stability to the material. This usually works and you can tear it off gently when you are finished sewing. Also, if the tensions are o.k., try using a ballpoint needle.

Need to now where to put tentions to sew sweat pants.


use a couple of pieces of waste material the same as the sweat pants material and sew about an inch long
adjust the needle tension and do it again
repeat the exercise until the top and bottom thread joint at the middle of the two pieces of the material
tension settings on the machine are a loose guide as the thread thickness, material thickness and needle size all have a bearing in the tensions of the thread
so practice and adjust prior to sewing is the way to go

Keeping the thread in needle when you begin to sew


after threading the needle pull about 6" of thread out the back under the press foot
that way the thread is jammed under the foot and is held in place for the next thread
bobbin thread should also be out the back
when you have finished sewing then lift the foot and move the material sewed about 6"" away from the foot before cutting the threads

Loose upper tension


Before you play with any tension dials... check your thread spool. If you are using an ordinary spool with the tread end catch cut into the rim of the spool and you don't orient that away from the direction of the thread travel... it can catch and cause you issues similar to what you mention.

So rethread the machine... making sure that catch is pointed toward the bottom of the spool pin and make sure that presser foot lever is up when you thread the machine.

Then do a nice long test stitch on the same type of material. If it is still giving you issues tighten the upper tension by small increments then re-test. If after a few times you still have this issue... examine the entire thread path for burrs and make sure the needle is the right type and size for your material and thread.

Good luck.

You need to sew the first stitch slowly. Lower the needle by hand and take up carefully. Pull the needle thread up and the bobbin thread should be caught in the formed loop and come with it. Pull them both to the back of the machine and sew.

Thread keeps breaking when sewing through thicker materials


When you sew any thick material on any machine the needle cannot form the loop properly as the needle comes up because the material is keep the tread tight to the needle, the only real way round it is to sew slowly.

Hello,

Although you already re-theaded and cleaned your machine, re-check this:

- Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your bobbin case. Re-thread your machine, reinsert and rethread your bobbin.

If that doesn't work, try this:

- Change your bobbin.There could be a nick along the edge of your bobbin spool that’s catching your thread as you sew.

- Raise your feed dogs if your machine has this feature.

Note:
when you start to sew a seam, hold the upper and bobbin thread tails. Hold them back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.

Hope this helps.

Hi I am pretty sure that the bobbin and the thread are in correctly but when I put the material in the needle just put holes in the material. what am I doing wrong?


you may have adjusted the upper tension and made it so tight that the thread just pulls out of the needle and needle makes holes in fabric. you might want to check the feed of the bobbin, it will not allow the machine to sew if it is not able to be picked up by the needle. the bobbin thread is usually (when held in your hand) with the thread coming counter clock wise. and then it will lay in the bobbin holder and the end of the thread will come back to about the slide catch thing and be held there until the needle thread catches it (leave the cover off the bobbin area until you watch and see what happens then. Try adjusting the bobbing tension too hope you understand what I mean here.

Bobbin thread not feeding into the upper needle thread


completely unthread the machine....ensure the needle piston shaft is in the correct position and retread the upper. reinstall the bobbin and turn the machine by hand to engage the bobbin thread. Draw the bobbin thread through the stitch plate and with the needle thread, allow to trail off the back. attempt to sew a piece of scap material.

please let me know what happens at this point.
