Conversion Notes
Cosmo 2311 is close-rated for DMC 938. At this extreme dark value, close-rated substitutes are generally adequate for most applications — very dark threads are harder to distinguish at normal viewing distance, and the warm-versus-neutral distinction that makes 938 special is less perceptible in the darkest value range. For designs where the warmth of 938 specifically contrasts with a neutral black element — where 938 is placed deliberately alongside DMC 310 and the difference in warmth creates depth or material differentiation — testing Cosmo 2311 confirms whether the close-rated substitute maintains enough warm character to produce the intended contrast. For standalone warm near-black applications in organic subjects where no direct comparison with neutral black is present, Cosmo 2311 performs adequately and the close rating is unlikely to cause problems in most finished work. Cosmo's silkier thread surface can give very dark warm-brown fills a subtle quality at this extreme dark value — the Cosmo construction holds even in near-black territory. For large dark fur, wood grain, and botanical shadow fills, evaluating Cosmo 2311 coverage consistency on your actual fabric before committing ensures the thread performs as expected at this extreme value. Cosmo's strong Asian market availability makes it the most practical option for stitchers in those regions working on dark-organic-subject designs. Anchor 1088 and Madeira 2005 are both preferable when available given their exact ratings; Cosmo 2311 is a practical alternative when exact-rated options are harder to source.

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 938 to Cosmo 2311
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 938 is unavailable and Cosmo 2311 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 938 and Cosmo 2311 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 938 and Cosmo 2311: 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.
