Conversion Notes

Sullivans 45209 is a close match for DMC 799 Medium Delft Blue. For Delft-inspired designs where consistency across large blue areas is critical — individual tile motifs arranged in a grid, full blue-and-white ceramic reproductions where the regularity of the pattern makes any color variation immediately apparent — verifying Sullivans 45209 in your fabric and light conditions before purchasing multiple skeins is advisable. Any shade variation between dye lots will be immediately visible in these design types because the geometric regularity of tile-pattern designs provides no visual disguise for inconsistent color. The clean, cool quality of Delft blue that distinguishes it from the warmer cornflower family is the primary character to evaluate in Sullivans 45209: a close substitute that reads with even a slight lavender or purple warmth shifts the ceramic reference from Delft to a different blue tradition. For Scandinavian folk art borders and traditional blue-and-white textile designs where 799 provides the primary medium blue without strict Delft ceramic specificity, the close match is more workable. The exact-rated Anchor 136 and Madeira 0910 provide more reliable performance for genuine Delft-inspired ceramic reproduction work.

Decision guide

When to trust DMC 799 to Sullivans 45209

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 799 is unavailable and Sullivans 45209 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 799 and Sullivans 45209 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 799 and Sullivans 45209: 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.
