How does the bobbin thread work in a Sewing Machine?

Sewing machine bobbins as well as thread bobbins are pivotal components of a sewing machine. The Lockstitch requires two threads that is i.e., an upper thread and a lower thread. The upper thread feeds from a spool and is threaded through the needle. The lower thread feeds from the bobbin which provides a loop for the upper thread to catch onto, completing the stitch. The stitch could be uneven or weaken over time if the bobbin thread isn’t operating correctly. Make sure the bobbin thread is wound accurately and threaded through the machine before beginning to sew on the 4-hole button. This will make it easier to guarantee a solid, even seam and a firmly fastened button.
