DMC 3850 to J&P Coats: Thread Conversion

J&P Coats 6187 is a close match for DMC 3850 Dark Bright Green — the same conversion number used for DMC 3848 (Medium Teal Green). This overlap confirms that J&P Coats' coverage is compressed in the dark blue-green zone, offering one thread where DMC offers two distinct shades. If your project uses both 3848 and 3850 as distinct values in a gradient or as separate design elements, sourcing both from J&P Coats will reduce or eliminate the distinction between them. Testing in-project is recommended before committing to this approach. For projects using only 3850 as a standalone dark teal-green, J&P Coats 6187 is a practical substitute.
