Welcome to the Quilting Board!
Make sure your bobbin is in correctly. This happened to me very recently. I scratched my head over what the problem could be, did all that should be done to check tension problems, etc. Then I took the bobbin out and replaced it with a new one - that I put in the right way. Problem solved.
A quilt is like a good life. It's full of mistakes, but, in the end, it looks pretty good.
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
my husband who is a former industrial sewing machine mechanic says to check the top tension and to make sure there is no lint in the tension disc for the top thread. Hope that helps
Clean your upper tension discs well. When you have wonky stitching on the bottom it is usually an upper thread tension problem. Fuzz or thread can get stuck in there and cause the upper thread not to fully engage into the discs.
It sounds to me like your upper thread tension is off. To verify, sew a bit on a test piece of fabric with different color thread in the top and bobbin. I am also thinking you might have something jammed in the tension discs. with the foot up, take a piece of strong thread and 'floss'. When you rethread your machine, your presser foot needs to be UP for the threading process, until you get to the needle. Give the thread a small tug to seat it in the discs, put the presser foot down. at this point you should not be able to draw the thread thru the machine. Then thread your needle.

I just took the machine apart, thouroughly cleaned every piece the thread touches and re-threaded the way you said to. My first ten lines of stitching came out great, then bam, all wonkey again!! I don't get it.Originally Posted by PaperPrincess
So sorry you are still having problems. It always happens in crunch time.
Did you use 2 colors of thread to verify we are dealing with the top thread or bottom thread? THat will really narrow down the issue.
One other thing. If it sewed OK for a bit, then started behaving badly, were you able to see if it was still threaded correctly? Did it stay in the tension discs? Did it jump out of the takeup lever?
When it messes up, it's a good thing to look over the threading before re-threading...
One other thing, did you try a different thread? I've found that some colors from the same manufacturer won't work in my machine. Usually it's a really dark color, and I think it makes the thread stiffer and more prone to jumping out of the take up lever.
I know lots of posters are saying to look at the bobbin, but I really think it's the takeup lever or the tension disks.

Does your machine use plastic bobbins? If so, try filling a bobbin just halfway and see if that makes a difference. Plastic bobbins can distort if filled too much over time.
