Conversion Notes
Cosmo 245 is a close match for DMC 815 Medium Garnet. Cosmo’s garnet shades can lean slightly more purple than DMC’s warmer, browner interpretation of the color — a documented tendency in the Cosmo red family that affects this specific position in the garnet range more than lighter or darker positions. In a design where 815’s warm, slightly brown-red quality is doing important work — distinguishing it from cooler, more violet-toned dark reds elsewhere in the palette, or maintaining the warm register of a heritage-style design that relies on earthier, less cool reds — this potential purple lean in the Cosmo version is worth testing before use in significant quantities. The specific test is to compare Cosmo 245 against the other reds in your palette in natural daylight: if it reads as slightly cooler and more purple than the DMC garnet family threads around it, it will look like a different family member. For heritage sampler reproductions where the warm, composed garnet quality is historically referenced, the exact-rated Anchor 22 and Madeira 0513 are preferable. For general dark-red fill and accent work where the purple-or-brown distinction is less critical, Cosmo 245 is workable in most practical conditions.

How We Validate This Match
This Cosmo page is meant to help you shortlist a replacement quickly, then verify the physical skein before you mix brands in the same stitched area.

- Source basis
- Approximate cross-brand floss mapping. Treat it as lower-confidence until you compare the physical Cosmo skein against the DMC reference.

Decision guide
When to trust DMC 815 to Cosmo 245
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 815 is unavailable and Cosmo 245 is good enough after a stitched sample check.
- + Shortlisting a Cosmo substitute before you buy skeins, especially if your project can tolerate small differences in sheen or dye lot.
- + Comparing this Cosmo 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 815 and Cosmo 245 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 815 and Cosmo 245: 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.
