DMC Colour Variations embroidery floss is designed for cross-stitch and surface embroidery when you want gentle colour movement without changing skeins. Each 8 m pull skein in Mystical Midnight (4245) produces subtle tone shifts along the stitch line and supports shading in motifs, borders, and lettering. Separate strands for fine detail or fuller coverage, and keep the floss clean and dry while stitching to reduce tangling.
