Iris Embroidery Thread, 1000m, in Flannel color, reference DXIP1219, 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 with 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 Flannel shade is a soft brownish-gray, associated with the texture of flannel fabric. It is a preferred option for embroidery with a more textile and cozy feel than a plain gray.
