Tension problems. Please help!
 

My Singer Superb just came out of hiding for the last two years. She has been cleaned and oiled. I keep having issues with the tension resulting in a very messy bottom stitch. I have double checked that my threading is correct, and have adjusted the tension tighter and looser with not perfect results. I would post a picture but I am on the site on my phone and don't know how to. Any idea what I am doing wrong?

Okay, try a new bobbin. Sometimes the bobbin doesn't feed right. And check to make sure that there might be a piece of thread in the bobbin area around where it is fed. And try a different thread, some machines don't like some threads.
Best I can do.

Also double check that the needle is in correctly

Needle is in correct and I am using my go-to thread, which is Dual Duty all purpose thread. Never had an issue before with it. I will try a new bobbin and see if that helps.

Wound a new bobbin and now I'm right back where I started with a very messing bottom thread. This is so frustrating. I have a limited amount of time to work on 3 baby quilts and it figures that my machine is going to give me problems.

How do I add pictures while on the site on my phone?

Are you sure it is the bottom thread with the problem? If you have issues on the underneath, it is sometimes the top thread tension causing the problem. If you are sure it is really the bottom thread, have you checked the tension on the bobbin?

When I sew, the thread you see on the top of the fabric is nice and straight and doesn't pucker and is not loose. Then I flip the fabric over, the stitching is all over the place, wobbly and loose. If I turn the tension all the way up it straightens out a bit but I shouldn't have to turn the tension all the way to the highest setting.

I'm also not sure how to check the tension of the bottom thread. There are no instructions in my manual that talk about bobbin tension.

I know it's teaching your grandmother to suck eggs, but start at the beginning re thread new needle and check bobbin in properly. Hope it works out for you x
