Conversion Notes
Cosmo 813 is a close match with a very slight cool tilt compared to the DMC original — warm enough for most purposes, with the mauve-pink character preserved, but carrying just a fractional shift toward a cooler reading than the warm rose quality of DMC 3688. This is consistent with Cosmo's general tendency in the mauve family: their equivalents tend to run a touch cooler and slightly less rosy than the DMC originals. For decorative floral applications and large fill areas where Medium Mauve appears as a dominant palette element, this slight coolness is typically absorbed by the surrounding design context and viewing distance, and the substitution reads as fully adequate. The slight coolness is most visible when 813 is placed directly alongside DMC 3688 in a side-by-side comparison; in context within a larger design, the difference typically absorbs into the surrounding palette without calling attention to itself. For carefully graded shading sequences where exact color temperature consistency across all values is important, a test swatch of Cosmo 813 alongside your other mauve-family threads helps confirm whether the slight cool shift creates a visible discontinuity in your specific gradient.

Decision guide
When to trust DMC 3688 to Cosmo 813
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 3688 is unavailable and Cosmo 813 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 3688 and Cosmo 813 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 3688 and Cosmo 813: 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.
