With your slide plate open, you will see 2 screws on the bobbin case. You need to adjust the one on the inside (not the one that sits at the edge of the metal strip). Do so very slightly. If you can't seem to get it adjusted, take a look and make sure there isn't any thread or lint in between the two pieces of metal that the thread feeds through. This can cause a loose tension.

Have a Singer 11910000A and the bobber thread bunches up and makes a mess in the feet when sewing


Is it really the bobbin thread that is globbing? Check closely. Usually it is the upper thread accumulating under the fabric.

If it is in fact the bobbin thread, then the bobbin case is not threaded correctly, the bobbin case tension needs adjustment, or it is broken and needs replacement. There are web sites and YouTube videos that show how to adjust the bobbin case tension.

QUICK FIXES: Remove all the thread from the machine. Clean the area around the feed dogs and bobbin area. Oil as instructed in the owner's manual using ONLY fresh, good quality sewing machine oil (only 1-2 drops each spot). Install a brand new needle insuring it is installed correctly. Avoid using fuzzy, old, or bargain bin thread. Rethread: Be sure you raise the presser foot BEFORE threading the upper thread so it will seat properly in the tension disk--and check to make sure you are threading the machine correctly. Check that the upper tension is set properly (the factory standard is usually the halfway point between the high & low number on the selection). Test on a scrap of the fabric you wish to sew. Adjust the upper tension--either tighten to pull the upper thread toward the top of the fabric, or loosen to pull more upper thread down.

Here are some web sites that may help.

New Home ss2015 machine. I am having trouble with the thread tension. I have loops on the bottom. I have cleaned the bobbin case, changed the needle, re-threaded and moved the upper tension all the way up....


try adjusting the top tension to 3 & if it doesn't stop the looping, try 4 but I wouldn't go any higher than 5,, if changing the top tension doesn't help then I suggest taking the machine in to have it serviced. the bottom tension is more difficult to do,, it's also very possible that the top tension dial is messed up & needs replacing. only a sewing machine shop can tell for sure.

My bobbin stitch is loose. I have tried adjusting tension and have changed the needle.


A. To correct loose stitches, try the following: (1) Balance the thread tension. If the stitches are loose on top of the fabric, decrease the tension to the next lower number. If they are loose on the underside set the tension to the next higher number. (2) Make sure the needle/upper thread follows the threading path. (3) Check to see that the bobbin case is threaded properly. (4) Use a different size needle. For fine fabrics, use a smaller needle (size 9, 11); medium-weight fabrics require a size 14 or 16. And use a size 18 or "Denim" needle for heavy corduroy or denim.

I am using black bobbin threaad with white needle


In my experience, I can adjust the tension on my older machines (like my Singer Featherweights so that the needle thread will not show at all on the underside of the fabric (and the bobbin thread will not show at all on the top)--but I've found it nearly impossible to get the same degree of control on my newer (computerized) machines. It always seems that there is a touch of the needle thread showing on the bottom and a touch of the bobbin thread showing on top.

I'm not familiar with the MegaQuilter but I'd just keep playing with your tension control to get it as fine as possible.

Good luck!

Thread mess at the underside of the fabric


Hi, maybe your bobbin is turning the wrong way and you need to flip it over. Or you don't have any top tension. Be sure the thread is in between the tension disks with the foot up. Its also possible that there is a burr on the hook part that goes around and grabs the top thread. The thread will catch on the burr and cause this issue. Usually after breaking a needle. Then the burr would need to be polished off.

Singer 301a...sews on top of fabric nicely...bottom is just loose loops of thread...it's like the bobbin is not sewing...I put 2 different colors in to see...top is perfect...on bottom of fabric I see the...


This is a tension adjustment problem. It's good to use two different colors of thread, like you did. From your description, the top thread (needle thread) tension needs to be tighter. As you tighten the tension of the top thread, you'll see that the top thread pulls the bobbin thread up into the fabric so it's no longer laying loose on the bottom of the fabric.

You'll need to have the pressure foot down when you tighten the tension. Tighten it a little, sew a practice seam, check to see what the stitch looks like. Tighten it a little more, sew, check, etc etc--until both top and bottom look the same--you shouldn't see much (if any) of the bobbin thread color on top of the fabric or the top thread color on the underside.

Let me know how this works for you, ok?

Ok, if the bottom thread is looping (bottom of fabric) try adjusting your UPPER tension.

Make sure that your thread isn't catching on anything before it reaches your needle, a small snag can cause needles to break.

Singer 57817 thread tension problem


Hello,

If you have Increased the upper thread tension on your machine, try these solutions.

* Decrease your bobbin tension if your sewing machine allows you to adjust it. Consult your manual.

* Re-thread your bobbin, It may be threaded incorrectly.

* Reinsert your bobbin, It may be inserted incorrectly.

* Change your thread. If your upper thread and bobbin threads are different types, try using the same thread for both.

I hope this helps.

Top thread will not pick up bobbin thread makes a big loopy mess


This is sometimes caused by the upper thread not threaded correctly. You need to thread it first with the pressure foot in the up position. You need to "floss" the thread into the clear plastic guide as this is where the tension is. The tension should be set to E for embroidering. Also make sure you get the bobbin thread in the slot on the bobbin case. Also, lower your pressure foot before you begin embroidering. Hope this helps!
