I have wasted over 2 hrs trying to figure this out !!
My machine is sewing a great stitch on the bottom but the top is ALMOST straight !! like its not going down in the material.
I have changed bobbin thread.....top thread.....new needle...adjusted tension ... and still nothing has fixed this !!
But the first 4 stitches are right then it goes almost straight.
Any advice?? I now have a headache lol :?: :?:

I am trying to piece a quilt so, 2 layers of cotton fabric.
I have rethreaded 3 times.
I have cleaned bobbin shaft free of lint.
Its got to be in the tension but I cant figure it out, I have adjusted alittle here and there but nothing is helping.
# 11 needle since I'm only doing 2 layers. (new)

What type of fabric are you sewing? How many layers? What size needle are you using?

Clean the path of the thread. You may have adjusted the tension, but if there is a small piece of thread stuck somewhere along the path, adjusting it will not help much.

Maybe clean any lint in the bobbin casing?

Check your bobbin to makes sure it is in correctly,Threaded correctly. But it seems like to me it is a tension problem. Good luck..I get what I call railroad tracks and that is tension. It has a bumpy feel and the top thread can be pulled out very easy as it is almost straight. BillsBonBon

Could your thread be catching on the little notch on the spool, thus not flowing freely? Try turning the spool around.

Need a new needle?

I would think that if the bottom is catching, the top would be right.
Have you checked the BOBBIN tension? That is on the bobbin case (where you put the bobbin).

Yes I have checked it to everything I know to do I have done lol ty :D

Check out your owner's manual, or go online to download it.
I never can find my manual, no matter which safe place I put it and have to look online. So far that's all the help I needed.
