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 have had more problems trying to wind the metal bobbins. I have tried every tension number to get the bobbin to wind and am still having troubles. I have a Singer sewing machine and have read the directions over and over and over again. Can anyone here help me please. I really need help with this as I live alone and have nobody else to ask. I would appreciate any suggestions given. Thank Again. Frugalsewer.
