Question about Singer 2638 Mechanical Sewing Machine
This can be caused by incorrect bobbin tension or the bobbin is in backwards. Take out the bobbin and put it in according to the instructions for your Singer. If you still have the same problem try tightening the bobbin tension. Please ask if you have any questions.

Look for the buttonhole lever, just in front of the presserlever, on the lefthand side of the machine. Pull it down and push it back to the top. Good Luck

SOURCE: backward stitching
Knowing which kind of machine you have helps alot. Just guessing but maybe the reverse mechanism is stuck and needs some oil in it to free it up. Or the buttonhole mechanism is stuck in reverse part of it.
Probably you should have it looked at.

Feed dog drive gear(2) are plastic and are probably stripped. Always replace them in pairs. While you are at it replace both hook drive gears as well. It will run as good as new.

Here are a couple of things to try.
* Un-thread your machine and remove your bobbin. Clean any loose thread or lint out of your
bobbin case. Re-thread your machine, reinsert and re-thread your bobbin.
* Change your bobbin
There could be a nick along the edge of your bobbin spool that’s catching your thread as you
* When you start to sew a seam, grasp the upper and bobbin thread tails. Hold them 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.
