Conversion Notes
Cosmo 814 is a close match for DMC 3687 Mauve. Cosmo's version trends slightly cooler than the warm DMC original — the rosy warmth of the DMC shifts fractionally toward a more straightforward pink-purple in the Cosmo equivalent, which is the characteristic tendency of Cosmo's mauve-range threads compared to their DMC counterparts. This is noticeable in side-by-side comparison but rarely problematic in finished work where the surrounding design context and viewing distance absorb subtle hue variations. For mid-tone fill work in floral designs — rose and peony petal bodies, full floral fills in garden-motif pieces — the slight coolness is typically absorbed by the surrounding palette. For the large stitch areas where Mauve typically appears as the dominant fill color in a design, Cosmo 814's softer hand is a practical advantage, making extended stitching sessions more comfortable. If you're mixing Cosmo 814 with DMC threads in adjacent positions of the same gradient, a test swatch confirms whether the slight coolness creates a visible transition discontinuity in your specific design context.

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.
- Methodology
- This comparison uses the site's source-of-truth record for DMC 3687, the stored Cosmo equivalent, and the saved close rating before rendering the page copy.

- 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 3687 to Cosmo 814
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 3687 is unavailable and Cosmo 814 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 3687 and Cosmo 814 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 3687 and Cosmo 814: 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.
