Good advice. Also, have you moved any tension knobs inadvertently?

One more suggestion, when you thread your top - always have your pressure foot UP, so the tension rings can accept the top thread - never have the foot in the down position!

All the above should help your tension problems.

This is what happens when the upper thread is not going through the tension discs and take up properly. Re Thread your top thread carefully and make sure it is correctly threaded and you should have no problems.

Agree with Heidi's reply. Good luck.

when mine does this i have found cleaning the bobbin case is the answer. and while i'm at it, i change the needle, something i rarely do. (oops)

this is a common problem caused by no thread in the take up lever. whenever you thread a machine the presser foot must be up and the needle in the highest position, if this is all good, you won't have the problem pictured.

I'm with the other quilters on this one. I had mine do that and I rethreaded the machine and I still had problems.
So I threaded up another bobbin and changed the needle.. worked fine after that.. Hope this helps

Don't hit me but was your presser foot down? Mine has three levels and sometimes I don't hit that last click to get it all the way down. Looks just like this. Otherwise I agree with starting fresh, new thread, new needle, clean bobbin case, etc.

The thread on the bottom is from the top. Your thread jumped out of the tensioner. Just rethread and you should be o.k.

[QUOTE: Have you tried to re-thread the entire machine, new bobbin, new needle and reset it back to factory tensions? That might help. Have you used this thread successfully before? If not, try one you have used.[/QUOTE]

I thought that my machine was completely broken, and I did what you said above, and MIRACLE! It works.

Everything but messing with the tension, which I never touch...

After all the re threading make sure your needle is all the way up into the holder and put in facing the correct way. Ask me how I know this. My needle did this when not quite all the way up into the holder!

Rethread your machine. If the issue is under the fabric it's the top tension and if its on top of the fabric its the bobbin tension. This happened to me this weekend and I'd been sewing for over an hour, stopped for a few and then this. Somehow the thread tension got messed up. I rethreaded and all is right with the world. I never have to adjust my tension though.

When the thread is going like that on the bottom - this means the top thread is your problem.... Try rethreading watching the the looper that goes up and down... that use to happen to me when I would sew and that thread would loop around the pull up threader ...

Well, I was having the same problem, plus my machine was eating my material. I finally figured it to be the bobbin. I had the wrong kind. Some machines are very touchy, so went to my machines booklet and got the bobbins number and bought 50 from ebay for 5.00. Now all is well. I had to rewind the old bobbins on to my new ones. I have two different machines with different bobbins, so marked my brother bobbins with marker red and pfaff blue. Am giving my other bobbins to someone else. Hope this helps.

Glad to hear that the suggestions worked! I have had the same problem with most of the machines I have or have had and when I do the things that have been listed above it usually works great..The last time I still had a problem and finally after going over the process again I found a thread that was hidden behind the tension disk..another time, another machine I found a small thread under the bobbin race..both of these looked like a tiny piece of lint and as I got a hold on them with a tweezer and pulled them out I found they were threads.. Happy sewing!!!
