DMC 3760 to Cosmo: Thread Conversion

Cosmo 186 is a close match for DMC 3760 that can skew a touch warmer and slightly lighter in some dye lots. Before committing Cosmo 186 to a large fill area, stitch a test section next to any DMC 3760 already in your project — the visual difference is usually minor and unlikely to be noticed in isolation, but it can register in a side-by-side comparison, particularly in the sampler border and geometric pattern work where Wedgwood blue's precise character matters most.
