Leather needles have a wedge-shaped or cutting point that slices a clean hole through tough materials like leather, suede, and vinyl, preventing the fabric from tearing or damaging the sewing machine.

Use a larger needle size (e.g., size 100/16 or 110/18) for thicker, heavy-weight leather and a smaller size (e.g., 90/14) for light-to-medium-weight leather and soft vinyl.

No, a leather needle should only be used on leather and similar materials; the cutting point will damage woven and knit fabrics by slicing the threads, leading to material weakness and tears.

Yes, a leather needle paired with a walking foot is the ideal combination for sewing leather, as the needle provides the piercing power while the foot ensures smooth, consistent feeding.

Use a strong, durable thread like nylon, polyester, or heavy-duty upholstery thread to match the strength of the material and ensure the seams of your leather goods last.
