Loading a bobbin is a fundamental sewing technique that involves winding thread onto a small spool called a bobbin. This bobbin is then inserted into the bobbin case of a sewing machine, where it provides a continuous supply of thread for the lower part of the stitch.
Loading a bobbin correctly ensures smooth and even stitching, preventing common sewing problems such as skipped stitches, thread breakage, and fabric puckering. It also contributes to the overall quality and durability of the sewn garment or item.
