Conversion Notes
Sullivans 45339 is a close match for DMC 3970 Dark Forest Green and is a perfectly serviceable option for dark anchor colors like this. The performance gap between Sullivans and premium brands is smallest at the extreme dark end of the value scale, and the deep, near-neutral forest shadow character of 3970 is less demanding to replicate than a subtly balanced mid-value or pale color. For a large landscape WIP where 3970 appears in significant quantities as the shadow foundation of tree and foliage fills, the Sullivans option can represent meaningful cost savings without visible quality difference in the finished work at viewing distance.

Best for

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 3970 and Sullivans 45339 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 3970 and Sullivans 45339: 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.
