S.I.N.Y. Goldwork Anchor Sweatshirt is made of 80/20 cotton/poly blend. Goldwork is the art of embroidery using metal threads. It is particularly prized for the way light plays on it. The term “goldwork” is used even when the threads are imitation gold, silver, or copper. The ends of the thread, depending on type, are simply cut off, or are pulled through to the back of the embroidery and carefully secured with the couching thread. A tool called a mellore or a stiletto is used to help position the threads and create the holes needed to pull them through.
