DMC 437 to Cosmo: Thread Conversion

Cosmo 2523 is a close match that performs well in accent and detail uses. At this lighter value, even a close-rated substitute generally functions without visible issue in most applications. The main caution applies to large fills: in a full teddy bear body or a large pastry background, stitch a small test area first to confirm that the Cosmo version reads as warm and balanced — not yellow or pink — in your specific lighting and fabric context.
