DMC 489 to Madeira: Thread Conversion

Madeira 1204 is a reliable close match with notably good colorfastness — a meaningful advantage for deeply saturated teal shades in display pieces that will receive light exposure over time. Madeira's quality in the dark blue-green range is consistent, and 1204 integrates well alongside the lighter Madeira 1205 (equivalent for DMC 490) if you're using both shades from the same brand in a teal gradient.
