Conversion Notes

Madeira 1109 is rated close for DMC 3766 and tends to sit slightly cooler — pushing more toward blue-green than the warm, airy teal that characterizes Light Peacock Blue. This coolness shifts the perceived character of the thread: the warm-tropical quality that makes 3766 evoke Caribbean water and hummingbird iridescence becomes a slightly more restrained, ocean-blue quality in Madeira's version. In small quantities used as accents, this usually doesn't matter. In large fill areas where the warm teal quality is defining the palette's character — a peacock motif's mid-feather fill, an expanse of tropical sea — the cooler reading can cause the design to feel less vivid and less warm than intended. If using Madeira for a peacock-heavy design, stitching a swatch and checking it in both natural and artificial light before committing to large sections is worthwhile to confirm the cooler version suits the design's specific palette character. For designs where a slightly cooler, more reserved teal-blue is acceptable or preferred, Madeira 1109 is a practical option.

Decision guide

When to trust DMC 3766 to Madeira 1109

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 3766 is unavailable and Madeira 1109 is good enough after a stitched sample check.
  • + Shortlisting a Madeira substitute before you buy skeins, especially if your project can tolerate small differences in sheen or dye lot.
  • + Comparing this Madeira 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 3766 and Madeira 1109 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

  1. Compare DMC 3766 and Madeira 1109: lay the physical skeins together in daylight before you mix brands in the same stitched area.
  2. Test on your project fabric: stitch a small sample so fabric color and stitch density reveal whether the match still holds at full coverage.
  3. 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.
