Thick threads, often made from polyester, nylon, or waxed cotton, are designed to provide strength and durability. Their impressive tensile strength ensures that the seams can endure the stress and strain that leather items often encounter. Leather, being a robust and flexible material, demands a thread that can match its endurance. Thick threads fulfill this requirement, rendering them particularly suitable for items such as belts, bags, wallets, and shoes.

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).
