Retread with the foot up but still having same problem
SOURCE: keeps "birdnesting", besides rethreading, how do I fix?
when you have bunching on the bottom, you have a problem with the top thread: no tension. (and visa versa) Make sure the thread runs through the tension discs, these discs are activated when you put the presser foot down, so you want to thread the machine with the foot up, also feel if there no burrs, hooks, or whatever, so your top thread comes smooth off the spool, no jerking.

Here is a diagram that shows how to do this.

Hello,
Here are some solutions to try.
* Re-thread your machine
It may be threaded incorrectly.
* Raise your feed dogs If your machine has this feature.
* When you start to sew a seam, hold the upper and bobbin thread tails back and out of the way as you sew your first couple of stitches. This will keep them from getting caught in your machine.
I hope this helps.

This happens when we forget to have the presser foot raised when threading.
What looks like the fault of the bobbin is actually the top thread not forming a tight stitch with the bobbin thread.
When the machine is threaded with the foot down, the tension control is closed and the thread cannot enter the control as it should. When you begin to sew, the tension control cannot do it's job.
If the machine is already threaded, lift the presser foot and pull about 10" of thread from the needle, or re-thread the machine with the presser foot up.

Sounds like you have the upper threading wrong, or you have the upper tension set too loose, set it to 5.
