Make sure that you have your thread going through all the proper thread guides when winding your bobbin. It sounds like the bobbin is getting wound with little or no tension and this can make a horrible mess when trying to sew. Take a look at your bobbins and make sure they look nice and tight. If they are too loose and you feel like you are following the thread path properly, just use your finger to tug on the thread a bit during the bobbin winding process to apply some tension and that should help.

I am having trouble getting the bobbin to function properly during sewing.


It could be the top thread is the problem. Might try removing all the thread. Consult the owner's manual for threading instructions. RAISE the presser foot BEFORE threading the upper thread so the thread will seat properly in the tension disk. Re-thread from the beginning carefully following the instructions--do not miss any spots or thread guides.

If top thread is still creating a mess of loops under the fabric, try tightening the upper tension. The tension is ideal when both upper and bobbin threads meet in the middle of the fabric.

Why does the top thread sometimes picks up the hook and then picks up bobbin but bobbin then crosses over and makes a mess? Wont work


Basic Tips for All
  1. Always turn the handwheel TOWARDS you (counter clockwise) as turning it in the opposite direction (away from you, clockwise) may knock the timing out requiring repair from a service center.
  2. Always be sure your presser foot is in the DOWN position before sewing. Sewing with the presser foot in the up position will cause your thread to tangle and your bobbin to jam.
  3. Change needles regularly (after 16 hours of use) as dull/weak needles can cause damage to your machine and fabric. Only use SINGER needles on your SINGER sewing machine.
  4. Always be sure you are using the correct bobbin for your machine. Class 66, Class 15 and Class 15J bobbins look very similar. However, using the incorrect bobbin class in your machine can cause damage.

Cant get my bobbin in right position it keeps knotting up on inside of fabric


Top thread problem, Not enough tension on top=loops on the bottom of the fabric; too little tension on the bottom = loops on top of the fabric. Yes, I know it seems backwards. See: http://www.picturetrail.com/sfx/album/view/22521551
Dollars to donut holes, you either threaded the top of the machine with the presser foot down (it has to be UP to let the thread into the top tension), or you're trying to sew with the presser foot still up (which is an issue common to people trying to sew bulky seams).

Take the thread off the top of the machine, take out the bobbin case and give the machine a cleaning, rethread the machine, fetch up the bobbin thread and hold the bobbin and top thread ends together under and behind the presser foot for the first 2-3 stitches of each seam.

Upper thread gets jammed in bobbin area


Try these suggestions
1. Change the needle--use a needle that's for the fabric being sewed
2. Rethread the machine--top --make sure to use every thread guide
3. try a different bobbin--make sure bobbin is inserted correctly into the bobbin case, & make sure the bobbin is turned the correct way in the bobbin case
4. make sure the thread has not come off the thread take up lever
5. Clean under the needle plate & in the bobbin area for lint or threads

I hit a pin with my Singer Stylist 7258. It jammed. I changed the needle, rethreaded it, and turned it off and on, but it snarls up thread under the fabric, and seems that the thread does not always loop...


Good that you changed the needle. Did you rethread just the needle or did you rethread the machine? You may have already taken these steps, but if not, here is what I would suggest:

1. Replace the old needle (which you did), even if it looks ok, as it may be bent or have a tiny burr or other damage that isn't easily visible. Make sure the needle is seated properly - facing forward and fully inserted.
2. **Completely rethread the machine, making sure the thread is going through the take-up lever. It can easily pop out when the machine jams, and you can't always see that the thread is out of place. That could explain why the thread doesn't loop properly around the bobbin.
3. Remove the bobbin and clean any knotted thread or lint from around the bobbin carrier. Canned air is great for cleaning the lint.
4. Replace the bobbin, making sure the thread-end is clipped neat, not frayed or knotted.
5. Try sewing on some practice fabric to make sure the stitches are going to form properly before returning to your sewing project.
Good luck!

Bobbin jaming up


Clean the bobbin area.

Thread the machine with the presser foot up - always,

Make sure the bobbin thread is feeding clockwise and through the guides on the bobbin case.

Lower the threaded needle down and back up while holding onto the thread end. This will pull the bobbin thread up. Hold onto both threads and pull under the presser foot and to the back of the sewing machine.

Hold on to the thread ends and lower the needle into the fabric, then press the foot pedal.

You may want to use a leader - a folded scrap of fabric that you sew to the edge of and then **** against the fabric you want to sew. Sew off the leader and onto the fabric and this will keep the thread from going down into the machine. You can have a few stitches between the two to make it easy to cut the leader away.

When you stop to adjust the fabric make sure the needle is down to anchor the fabric (turning corners, sewing a curve. etc).

The slightest movement of the fabric when the needle is up will sometimes cause a thread jam.

Bobbin thread bunches up creating a tangled mess under the plate


This could either be due to the bobbin being wound too loosely, or the tension on the top thread is too loose. This just happened to me the other day, and I thought it was the bobbin thread, but then I put another bobbin in with a different color than the top thread (this is a huge help in diagnosing thread issues), and I was surprised to find that it was actually the top thread that was a big loopy mess on the underside of the fabric. I fixed it by tightening the tension on the top thread (quite a bit), and everything was fine.

Bernette sewing machine making a mess of thread on back of fabric


I once heard from a great sewing instructor that if the problem is on the back of the fabric then it is a spool to needle problem.... if the problem is on the top of the fabric, then it is a bobbin problem. Check your machine for dust and stray threads. Check your bobbin casing for dust and stray threads.

Fabric not feeding and jamming occurs


When this happens it is because the thread tension was not right so it gets stuck under the bobbin case and the feed dogs. Use a bigger lint brush and take out the bobbin casing and clean out the shuttle. When you rethread pull slightly on the thread before you feed it through the needle. This will make sure the thread is properly in the tension discs.
