[Kaderin Triste]

It's been a while since I've used my machine tbh.
I know that mostly I'm just spewing excuses because I'm a little scared of wasting fabric on stupid practice stuff. I need to test the tension the way we learned in middle school home ec to be sure, but I think it was possibly weird loops all around last time.
I know that solutions can be googled and that there are more experienced people here that I can ask. I don't know why I don't do it.

Okay, so just double checked and I wouldn't necessarily say "weird loops" but the top and bottom threads are showing on both sides. Like a little dot kind of? Mostly it's the top thread showing on the bottom that's the worst though.

Note: Just adjusted bobbin tension slightly and also tried out different tension settings on the top also. Nothing is helping the problem.
I have taken pictures of the problem (in case they're needed), but should try to find my sewing machine manual. I think it some tips for this kind of thing.
