Hi, using a jonome finesse model 356, changed the thread on the bobbin and now its knotting up and not loose from the bottom, did i thread it incorrectly? tension is wrong now?? thanks!

That is a tension problem. The bobbin tension is probably too loose, or you need to increase top tension.

It can also be bad thread.

Knotting occurs when your top thread and bottom thread are not properly contacted or do not interact correctly. Whenever knotting happens, you will notice that thread will bunch underneath the fabric. You can try re-threading the upper part of your sewing machine, making sure the thread is passing through every single thread guide on its way to the needle. If you find yourself constantly adjusting the tension of your bobbin thread, check the bobbin itself. Plastic bobbins especially can wear, causing them to grow loose within the bobbin housing and making it difficult to maintain correct tension. Try switching to a new metal bobbin and see if that resolves your issue.

Threading and setting the tension on your Finesse 356 sewing machine can be done by following these steps:

1. Raise the presser foot and thread the machine:

• Take the end of the thread from the spool and pass it through the tension disk at the top of the machine.
• Next, guide the thread through the take-up lever and then down through the thread guides on the front of the machine.
• Pull the thread through the needle from left to right and make sure it is securely in the needle's eye.

1. Set the tension:

• The tension dial is usually located on the top or the side of the machine, near the needle.
• To set the tension, turn the dial until the numbers on the tension gauge line up with the red indicator line.
• The tension should be set to a medium setting, around 4 or 5, but you may need to adjust it based on the type of fabric you are using.

1. Test the tension:

• To test the tension, sew a few stitches on a scrap piece of fabric, and then examine the underside of the fabric.
• If the thread is too loose on the underside, turn the tension dial to a higher number. If the thread is too tight on the underside, turn the tension dial to a lower number.
• Repeat the process until the thread is properly tensioned on both the top and bottom of the fabric.

If you have any difficulty with these steps or if you have any other questions about your Finesse 356 sewing machine, I would recommend referring to the machine's manual for more detailed instructions.

1. Do you mean that there are knots in the bobbin thread?
2. Is the bottom thread in your stitching looping and knotting.

If yes to 1. you need to rewind your bobbin fresh, and keep slight tension on the thread reel that you are winding it from. Put the handle of your scissors into the top of the reel to apply a gentle pressure while winding. Keep your eye on the bobbin as it winds and give it a nudge with a finger tip to ensure it winds the bobbin evenly top, middle and bottom.

If yes to 2, then you need to check your bobbin threading, is the thread even under tension. Is the bobbin tension set correctly. Break out your manual and revisit this to ensure it is set correctly.

What you have going on is a bobbin problem. The knots are referred to as birds' nests and happen when your bobbin thread gets caught on a piece of the bobbin casing. The large, loose stitches are normally caused by a problem with the bobbin case, a bobbin that is would properly, or when you're getting to the end of the bobbin's thread and the thread is loosely would on the bobbin at that point.

You're best bet is probably to buy a new bobbin casing. They're usually about $25 or so and you should be able to find one on eBay by searching for Singer (your machine name and model) under the Crafts category. The silver plate on top of the area covering where you place your bobbin into has screws you need to carefully remove (careful not to loose them!). If you need to, take pictures with your cellphone or digital camera as you remove the old bobbin casing so you can see how to put the new one in.

This should take care of the problem. If, for some reason it doesn't, you may well have a problem ALSO with your bobbin tension, and that should be looked at by a Singer Technician. You can find one in the yellow pages near you or probably by searching Yahoo Local. Happy Sewing.

Hi. It may be that you need to adjust the tension. Put a different color thread on top than is in the bobbin and sew a couple of inches, then check. I suspect you'll find that the top thread is the one that is loose and knotting up. (It's hard to tell unless you're using two different color threads.) If that's the case, your upper tension needs to be tighter. Tighten it just a bit, then sew a few more inches and check again. Repeat until you don't see any of the top thread on the bottom (or maybe just a little bit) or the bobbin thread on the top (or maybe just a little bit.).

Hope this helps!

Recheck the top thread and bobbin tension for equal balance of thread when sewing. The knotting of thread problem is usually because the tensions are too tight or too loose and/or thread may not be properly threaded. Another reason is when the bobbin thread is wind imbalanced it will cause the thread to knot-up when sewing. This problem is notorious when the bobbin is winded within the bobbin case on some machines. The bobbin thread need to be wind smoothly in the bobbin to avoid this problem.

Check that it is threaded correctly (both top and bottom) making sure that the upper thread is in the takeup lever. Watch the needle as you slowly turn the handwheel counter clockwise (toward you) and the needle point touches the fabric (make sure presser foot is down). Is the thread still relatively taunt? If it is loose, the upper thread tension unit does not have enough tension. Check the areas where the thread goes and make sure you remove any loose threads or fluff which could be inhibiting the tension discs from closing over the thread. If the tension unit still is not tightening enough, the tension unit may need to be replaced or the circuit board replaced. If everything is ok in the upper thread area, now look at the bobbin area. With no fabric, watch as the needle enters the bobbin area. Does it go down and the upper thread catch the bobbin thread and pulls it to the surface? Check for anything preventing the bobbin thread from being pulled up to the surface through the needle plate. If you have still not been able to resolve the problem suggest you take it to an authorized husqvarna viking dealer for service.

Good luck.

Thread test
Test your thread quality to start, thread your machine and LIFT the presser foot (this opens the tension disks). Pull your top thread straight back. If you feel no tension no mater how much thread you pull, your thread is good. If that your machine passes that test, then let me know, we can go to step 2. If not, try different spool of thread, same test until you get a smooth pull (tip: always check your thread this way when you thread your machine)
Step 2:
Pull on your threaded bobbin thread while it’s in the machine. Does it pull smooth and even? If so, go to step 3. If not, try a new bobbin (bobbins get bent or distorted if wound too tight).
Clean thoroughly in the hook and bobbin case area and oil 1-2 drop is all.
Thread knotting on the bobbin can be a lot of things but here's some guidance:
Tension:
If the thread is loose on the bottom of the fabric, it's actually the top thread is too loose. Think of 2 little elves playing tug of war in your machine, one on toip and one underneath. If you have loops on bottom, the top needs to pull harder (tighten top tension)
Jamming bobbin case:
If it is damaged from turning out of place once, it could have rough spots on it that makes the thread hang on it, and keeps making it turn over and over. Use a finger nail board (fine sanding) and smoothall rough spots. Then reset the bobbin case taking care to put the notch in the bobbin case in alignment with the proper spot in the machine (basically 5 o’clock) when looking at the round area where the bobbin case goes.

"Birdnesting" occurs when there is no tension on the needle thread to pull the bobbin thread. This is easily corrected by rethreading the machine, following the threading path carefully and making sure the thread is fully engaged in the tension mechanism.
