For crowns, jewels, swords, armour and light lines in tapestry pictures, DMC Diamant is the most durable metallic thread: single-strand, non-divisible and on a 35 m spool, so it stitches among the wool without breaking. This category holds the Diamant colours for tapestry; the full guide and comparison are in DMC Diamant. For wide shimmering areas use Light Effects or Etoile.
Use 3–4 threads together for half cross on 10–12 ct canvas, 2 on 14 ct and 1 in petit point; to reach wool height, mix Diamant with 2 strands of floss. The more efficient method is couching: lay Diamant on the surface and catch it down with tiny stitches in floss, giving swords and crown edges a straight gold line. Use a size 20–22 large-eye blunt needle and 35–40 cm lengths. One spool covers all the metallic accents of a medium tapestry.
