Before you begin sewing, it is crucial to prepare your leather properly. Start by cutting the leather pieces with a sharp rotary cutter or scissors designed for thick materials. Use a cutting mat to protect your surfaces and achieve cleaner edges. Additionally, consider using a ruler and a straight edge to ensure precise straight cuts. Since leather edges can be rough, you may want to use an edge beveler or sandpaper to smooth them out before sewing.

First, let me clarify this question I frequently bump into: this is a type of sewing machine designed to handle tough fabrics and thicker materials such as denim, canvas, and leather - better.

Heavy duty sewing needles are specially crafted to sew through multiple layers of fabric, heavy materials like denim, upholstery, leather, and canvas. The most notable difference between standard needles and heavy duty needles lies in their construction. Heavy duty needles have a thicker shaft and a larger eye, which allows them to accommodate thicker threads and withstand greater tension without bending or breaking. They come in various sizes, with the most commonly used sizes ranging from 90/14 to 110/18, indicating their increased strength and capacity for thicker materials.

Beyond speed and efficiency, high-speed overlock sewing machines play a crucial role in enhancing the quality and aesthetic appeal of finished garments. The clean edges produced by overlocking not only improve garment durability but also elevate the overall look by providing a polished finish. High-quality seams are vital for meeting customer expectations, particularly in the fashion industry where the slightest flaw can lead to significant dissatisfaction and returns.
