Iris Embroidery Thread, 1000m, in Dynasty Blue, reference DXIP1316, is a machine embroidery thread. Iris is a thread brand founded in 1954 in Monterrey, Mexico, originally dedicated to cotton threads for embroidery, knitting, and crochet, and today also offering trilobal polyester threads for machine embroidery. This 1000m thread is made of trilobal polyester, which is more resistant and shiny than traditional cotton, designed for high-speed embroidery and sewing machines. The Dynasty Blue shade is a deep and imposing blue, almost a royal blue. It is a preferred choice for embroidery that requires a more intense and solemn blue than the lighter blues in the same range.
