Conversion Notes
Sullivans 45437 is rated close and is functional for standalone Medium Lavender Blue projects where the complete lavender blue gradient is sourced from Sullivans for internal consistency. Sullivans' characteristic sheen interacts interestingly with this mid-value blue-violet — the surface luminosity adds a quality that suits the mid-sky position in landscape work, where a touch of atmospheric brightness is appropriate, but may feel less right for the matte, controlled quality that makes 3839 work in heritage and pastel designs. For daytime sky midtones, draped blue fabric in portrait-adjacent designs, and the primary fill in simpler single-color lavender blue patterns, Sullivans 45437 covers the territory adequately. Dye lot consistency is worth confirming when sourcing multiple skeins for large sky panel fills, as the subtle blue-violet balance can shift slightly between production runs at mid-value saturated colors. For gradient sequences where the value and hue relationships between all three lavender blue family members must be precisely maintained, the exact matches from Anchor and Madeira are the stronger options, as the close match carries more risk of visible drift where adjacent values meet.

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 3839 and Sullivans 45437 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
- Compare DMC 3839 and Sullivans 45437: lay the physical skeins together in daylight before you mix brands in the same stitched area.
- Test on your project fabric: stitch a small sample so fabric color and stitch density reveal whether the match still holds at full coverage.
- 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.
