This pack contains 4 Medium 80/12 Titanium Quilting Needles. Titanium is the latest technology in machine needles. The titanium coating dramatically increases the strength of the needles surface, improving the durability of the needle point significantly. Quilting Needles use a specially designed point and scarf to minimise any damage to the fabric and prevent skipped stitches when sewing through quilts. For patchwork or piecing, we recommend Hemline Sharps Needles.
