DMC 921 to Sullivans: Thread Conversion

Sullivans 45267 is a close match for DMC 921 Copper. As a lit-surface fill in copper gradient work — where 921 covers the sections of fox fur or autumn leaf that face the light source — coverage consistency matters: any variation in stitch density reads more in brighter, lighter areas than in darker shadow zones, where coverage gaps are more easily hidden. Monitoring even coverage when using Sullivans in the lighter positions of a copper gradient prevents the visual unevenness that can affect the highlight effect's credibility. The close rating at the 921 position in the copper sequence is more consequential than at the dark shadow end — the lit highlight is what the eye goes to first, and any color character difference between Sullivans 45267 and DMC 921 is most visible where value is highest. A test swatch of at least 4cm by 4cm on your actual fabric under typical display lighting conditions is the most reliable way to evaluate whether Sullivans 45267 reads as the correct warm copper-orange at the fourth gradient step. For designs where 921 covers the largest lit fill area in an autumn or fox design, both color quality and coverage evenness deserve confirmation before committing to full fills. For designs where 921 is used in smaller quantities as a secondary warm highlight or accent rather than a dominant fill, Sullivans 45267 is a more practical substitute where the close rating is unlikely to cause visible problems. Maintaining Sullivans brand consistency through all five copper family values produces more predictable gradient results than mixing Sullivans at individual positions with DMC at others.
