Iris Embroidery Thread, 1000m, in Brown Crystal color, reference DXIP1376, 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 Brown Crystal shade is a brown with a slight sheen, unlike a traditional matte brown. It is a preferred option for embroidery projects seeking a brown with an extra touch of luminosity.
