DMC Light Effects Thread. 1 skein of 6 strands, 8 metres long of premium DMC thread. The range consists of metallics, sparkly jewels, pearlescents, glow-in-the-dark and fluorescents. For full effect thay can be used on their own or for a more subtle finish they can be blended with another DMC thread. The threads have the same colour numbers as stranded cotton and can easily be substituted in a project.
