DMC 805 to Cosmo: Thread Conversion

Cosmo 142 is a close match for DMC 805 Medium Delft Blue. For designs where 805 serves as the primary or sole Delft blue — filling the large visible surface areas of Delftware motifs — Cosmo 142's subtle differences from the DMC original are worth assessing in a test swatch before large-area use. The workhorse nature of 805 in Delft designs means any shade inconsistency will be most apparent in this thread's fill areas.
