Conversion Notes

Sullivans 45365 is a close match for DMC 3721. At this darker value, the Sullivans sheen is less dominant than in lighter colors — color density absorbs additional surface reflectance, reducing the visible difference between sheen and matte at deep values — but still adds some surface luminosity that differs from the matte DMC finish. At the depth of Dark Shell Pink, the slight sheen can actually be a subtle positive: it gives the deep rose-pink a slight jewel-like quality rather than a flat matte shadow, which can read as more complex and beautiful in the finished piece. For shadow positions in floral work where 3721 needs to recede convincingly while maintaining the warmth of the shell pink family, the sheen difference is a minor consideration compared to the depth and warmth factors. For standalone Sullivans projects where all threads carry the same surface character, 45365 performs cleanly in shadow positions. For mixed-brand projects where Sullivans 45365 sits alongside matte DMC threads in the same gradient, the surface difference is less visible at this dark value than it would be for lighter threads in the same palette.

Decision guide

When to trust DMC 3721 to Sullivans 45365

This page is strongest as a decision aid, not as a guarantee that two branded skeins will vanish into each other without testing.

Best for

  • + Replacing missing floss when DMC 3721 is unavailable and Sullivans 45365 is good enough after a stitched sample check.
  • + Shortlisting a Sullivans substitute before you buy skeins, especially if your project can tolerate small differences in sheen or dye lot.
  • + Comparing this Sullivans candidate against the other conversions and nearby DMC shades linked from the page before you commit to a full swap.

Watch for

  • ! Close matches are not safe to assume interchangeable in focal areas without a physical test on your fabric.
  • ! Brand sheen, strand thickness, and project lighting can make DMC 3721 and Sullivans 45365 look further apart than the stored match rating suggests.
  • ! If the design depends on smooth gradients or skin-tone transitions, compare this swap against the neighboring DMC shades before you substitute a large block.

Before you commit

  1. Compare DMC 3721 and Sullivans 45365: lay the physical skeins together in daylight before you mix brands in the same stitched area.
  2. Test on your project fabric: stitch a small sample so fabric color and stitch density reveal whether the match still holds at full coverage.
  3. Keep a fallback ready: if the swap feels off, use the linked related DMC shades or another brand conversion instead of forcing the closest stored match.
