Threading the machine?

If the top thread is not pulling up the bobbin thread, is it actually catching the bobbin thread? If not, then the machine may be out of time. Search for sewing machine timing or take it for service.

If it catches the bobbin thread but then the bobbin thread is difficult to pull, then possibly there is a snag somewhere that is catching the bobbin thread, the bobbin tension needs adjustment, or the bobbin case is incorrectly threaded.

Be sure to use a brand new needle. A bent/damaged needle may not connect with the bobbin thread.

If it still does not pick up the bobbin thread, your machine most likely has a timing issue (the needle arrives at the wrong time to intercept the bobbin thread). There are multiple web sites and videos that discuss sewing machine timing. Or take it for service.

The thread needs to be hand wound on the bobbin first. Then hold the thread tail while activating the bobbin winder. There are machines that automatically wind bobbins but they are specialty machines and have no external bobbin winder mechanism.

maybe your machine needs to go in for servicing just to be safe it is possible some thing simple

NOTE TO THE QUESTION. Bobbins do not catch thread. A hook underneath when you use the wheel to advance the machine will come and catch the under thread OR BOBBIN THREAD and pull it up.
Something common and I do it, wrong bobbin in the bottom thread. I have 2 sewing machines so put thread on both plastic and metal bobbins and then just grab the wrong machine bobbin.
If this is not the issue, take the machine apart and clean it well. Note the spots that you are to oil SPARINGLY.

Hi there,

Well you may please follow the steps below -
1. Remove the bobbin from the sewing machine. Note: whether you have a drop-in, front or side-loading bobbin on your sewing machine. A drop in bobbin will load from the top, may be via a removable bobbin case cover near the machine-fed dogs. A side or front loading bobbin needs to be loaded into a removable bobbin case under the machine.
2. Choose the right size bobbin for the sewing machine.
3. Wind thread onto your bobbin. Your sewing machine should have a standard thread spool to hold the thread and a short, squat post wide enough for a bobbin.
4. Put the thread and empty bobbin into position on your sewing machine. Wrap the thread around the bobbin to start it. On most machines, disengage the needle by turning the smaller hand-wheel on the machine toward you. Push the bobbin post into position, securing the bobbin into place. Press gently down. Thread should begin to wind neatly onto your bobbin.
5. Break the thread, push the bobbin post back into an inactive position and remove the bobbin. Tighten the hand-wheel. Thread your sewing machine again if necessary before loading the bobbin.
6. Remove the bobbin case cover and put the bobbin into position. The thread should slide through a catch on the bobbin case and up through the cover.
7. Access the bobbin case for a front or side mount bobbin. Lift the catch and remove the removable bobbin holder. Put the bobbin into the holder and run the thread through the holder, bringing it to the front. Lift the catch and slide the bobbin holder back into the case. Hold your needle thread gently forward with your left hand and turn the hand-wheel. The needle thread will pass down into the machine and catch a loop of the bobbin thread. Pull this loop up and slide both threads to the back before beginning to sew.
Good Luck!!

Thanks for using FixYa!!

try a new needle
make sure the bobbin is not warped
make sure the bobbin case area is free of lint or loose thread
make sure you hold the upper thread tail while it's going down to pick up the bobbin thread
make sure there is a 2 to 4 in tail for the upper thread to grab

your needle may be in backwards

sounds like your keeping the upper thread too tight when you drop your needle down to catch the bobbin or the bobbin thread that you left hang out is too short, let me know if it works amy
