Why won’t my singer pick up the bobbin thread?
First, make sure the bobbin-winding spindle (located on top of your machine) has been pushed back to the left for sewing. If it is not in the correct position, the needle will not go down and pick-up your bobbin thread. … If the timing is out, the needle thread is not meeting the bobbin thread in time to form a stitch.
There’s also the thread from the bobbin. It’s located at the bottom of the sewing machine. This thread comes up through the needle plate. Thread from the spool goes through the needle’s eye.
