Titanium adds strength and durability. The strengthened shaft helps to reduce needle bending as it penetrates the multiple layers of fabric. The embroidery needle is specially designed for machine embroidery using rayon, polyester or cotton machine embroidery threads. This needle features a wider hole to allow the thread to pass freely. Another feature is a pontoon scarf with oversize bump to reduce the chance of skipped stitches which can result when fabric is flexing up and down rapidly with the fast moving embroidery stitch.
