Conversion Notes
Sullivans 45048 is a close match in the very dark mahogany range, covering the near-black warm red-brown territory. The close rating reflects some potential variability in the red undertone that defines 300's character — a substitute that loses the red fire and becomes a generic very dark brown misses the thread's essential quality entirely. The test: compare Sullivans 45048 against a neutral dark brown like DMC 898 (Very Dark Coffee Brown) on your project fabric. If the two threads read as similar, the Sullivans version has lost the red warmth and won't serve the glowing, rich role that 300 is meant to play. If the Sullivans version reads as clearly warmer and more red-tinged than the neutral dark brown, the warmth is present. Coverage with Sullivans may run slightly differently from DMC due to differences in thread construction and twist density, which at a very dark value determines whether the stitch reads as solid and opaque or as slightly transparent with visible fabric showing through. Test coverage with two strands on your project fabric before committing to any large shadow fill area where incomplete coverage would show as distracting white specks in the dark mahogany areas. Note that with two confirmed exact-match options available (Anchor 352 and Madeira 2304), those are preferable for precision work.

When to trust DMC 300 to Sullivans 45048
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

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 300 and Sullivans 45048 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 300 and Sullivans 45048: 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.
