Before beginning any project, preparation is essential. Artisans should accurately mark the stitching lines on the leather and ensure that their machine is properly set up. Tension settings on the machine must be adjusted to suit the thickness of the leather, which can significantly impact the stitch quality. As the artisan feeds the leather through the machine, maintaining a steady pace and consistent pressure will help achieve better results.
The mechanism behind a lock stitch is quite fascinating. When you engage the sewing machine, the needle thread passes through the fabric. As the needle descends, the bobbin case rotates and the bobbin thread is pulled up through a small opening. This interlocking action occurs as the needle rises again, creating a tight, locked seam. The configuration of these threads and their interaction with the fabric results in a stitch that is flat on one side (the top side where the needle is) and slightly bulkier on the other side (the bobbin side).
3. Adjust Tension Settings Depending on your machine, you may need to adjust the tension settings to ensure that the stitches are even and secure.
