Iris Embroidery Thread, 1000m, in Crayon Yellow, reference DXIP1314, 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 Crayon Yellow shade is a bright and uniform yellow, similar to the yellow of a crayon. It is a preferred choice for children's embroidery or cheerful designs that require a direct and solid yellow.
