Diamant Thread
From DMC:
Diamant metallic thread is a smooth, single-strand, non-divisible thread, that adds instant shine to any needlecraft project. This soft, tangle-free floss will keep it’s twist as you stitch, allowing it to glide effortlessly through nearly any fabric - whether it’s cotton, linen, silk or satin - and making it perfect for both cross stitch and traditional embroidery. One strand is equivalent to two strands of DMC’s Stranded Cotton Embroidery Thread.
