The thread you hold should break after a good layer or two (1/8 of the bobbin is wound..or close)...that's normal.
Breaking or stopping winding..is the thread breaking, or is the winding just stopping? If it just stops winding...does the bobbin pop back, or just sit there?

If the bobbin just stops winding...check that it's down all the way (holding the thread can cause the bobbin to rise a bit from the stress on the thread tail you are holding), and that the little white post that stops the bobbin when it's full is not turned to far...it can limit bobbin fills as much as half. I turn mine to where the top of the post is turned to almost the thinnest part. This let's me get the bobbin almost 3/4 full.

You don't want to fill plastic bobbins more than 3/4 full...it may cause them to crack and break (too much pressure).
Also, when winding invisible thread...I only fill half way...that poly or nylon thread can really cause a lot of issues on plastic bobbins.

I also have Singer machines...and it took a bit to learn how to use the plastic bobbins. I also have commercial machines (upholstery, 12 needle embroidery & Longarm)...and they all have their quirks for winding their bobbins.

Keep at it...and stay with this group...they are really helpful!

I was wondering too why you were adjusting the tension to wind the bobbin. I have never heard of that.

You might consider taking your machine to JoAnns and ask them for help learning to wind the bobbin. Most of the employees have been sewers for years. If they can't help, try contacting your local quilt guild. Sewing education is usually written into their by-laws, so ask them for help. If you still need help, I will try to help by PM. Let me know. -Kelly

You know the place where I bought my machine discouraged the prewound bobbins, they sold them, but did not like them. If you can manage to get a tightly wound bobbin you can sew much better.

I'm confused...what does the tension have to do with winding the bobbin? I don't have a Singer. I have a Janome, but tension should not be the reason for the problem you are having. Hmmmmmmmm.

Agree with Dog House Mom: Are you putting the thread through the tension disks? My threads goes through a separate hook on the opposite side of my machine so that it comes off the spool and down to the bobbin "hook" and then up to wind on the bobbin. Good luck.

Just be sure to hang on to the pesky thread so it doesn't slip away, for just a few seconds, then I trim it just a bit, or trim after the bobbin is wound. Don't feel bad, I sometimes have to thread the needle 5-6 times before I get it right. Merry Christmas.

All my machines have the thread go through tension as it is being wound onto the bobbin. But it is not the same as the tension disks for sewing. The thread goes through special tension disks for winding bobbins, and it is not adjustable on any of my machines.

You are doing the same thing that I do with the metal bobbins for my Singers. Once the tread breaks when I hold it, I just let it continue to wind. The one thing that I have found with new bobbins is that they maybe too big for the bobbin case.

Another problem is that you may be winding the bobbin too tight. I have started using a separate bobbin winder and that problem is gone.

Good luck.

Another thought came to me there are a couple of different sizes of bobbins, although by mistake I have bought them, filled them up put them in my bobbin case, the machine sewed but not well. If it were a matter of thread and I thought my thread was old and it would have to be fairly old I would get rid of it. Now one thing I do stay away from is the cheap thread, do not trust it. Good luck, what a pain for you, I know little things sure make a difference with machines.
