The tension on the bobbin thread seems to be loose, though I haven't done anything differently than usual. Such that the bottom thread is squiggly while the top thread is fine. How do I fix that? I have a basic White sewing machine.

Two thoughts -
1 - has the bobbin thread come out from behind the tension spring inside the machine? Reinstalling the bobbin sometimes fixes things.
2 - is it possible the bobbin wasn't correctly wound? Sometimes if the bobbin thread isn't wound properly all the way through, it can hit some areas of loose or tangling.

I'm not familiar with White machines but with my Singers causes can be: 1. Improperly wound bobbin 2. Bur on the needle 3. Bobbin tension too loose 4. Lint build up around the bobbin carriage I have 2 antique treadle machines that work perfectly most of the time, a portable I bought in Dec. '73 and DH's mom's portable no one wanted after she passed. The '73 machine is the one I use most and when it misbehaves, I can usually smack it with the palm of my hand and walk away. When I come back, it has usually "learned its lesson" and works well.  |

I will have to dig up my manual and see if there is a way to adjust the bobbin tension. Maybe the bobbin thread didn't get wound properly.
Is it possible that the upper thread tension is too tight? Would lowering that balance things?

There is usually a little screw on the bobbin case. Try to tighten it a little.

I don't have White machines. Kenmore Singer and Elna. On the Kenmore I looked at the owner manual and youtube videos on loading the bobbin thread correctly. The thread on the Kenmore needed to be wound in the opposite direction to the direction of the slot and opening on the bobbin to give it more tension. (so it needs to be placed so it is clockwise or counter clock wise) As said above, brush out the bobbin area, less lint, much better. The service manual will give you the place (the screw to turn if there is one) to adjust the tension (also mentioned above). Such a good thread about....thread. As you said snoozy, there is some interplay between the top and bottom (bobbin) threads so if the tension of the stitching is too loose on the bottom of the fabric, tighten the top tension a bit. The two tensions need to meet in the middle so that the top and bottom look the same and the threads cross over in the middle. Also check the pressure of the pressure foot, to make sure it is firm enough to hold the fabric against the feeders. |
