Quilting needles are engineered for piecing and stitching through multiple layers of cotton fabric and batting. A strengthened, slightly longer shaft helps reduce deflection as the needle pierces layered seams, supporting straight, even stitches on domestic machines. Size 90/14 suits medium‑weight cottons, backing and typical quilt sandwiches used in everyday patchwork, sashing and borders. Choose size/type to match fabric and project needs.
