Threading a bobbin is a fundamental sewing technique that involves winding thread onto a small spool, known as a bobbin, which is then inserted into the bobbin case of a sewing machine. The purpose of threading the bobbin is to ensure a continuous supply of lower thread during the sewing process.
Threading a bobbin correctly is essential for the smooth operation of a sewing machine. An incorrectly threaded bobbin can lead to tension issues, skipped stitches, or even machine damage. Moreover, it plays a crucial role in achieving optimal stitch quality and preventing thread breakage during sewing.
