DMC 915 to Cosmo: Thread Conversion

Cosmo 261 is a close match for DMC 915 Dark Plum. The close rating may reflect a subtle shift in the red-versus-purple balance — Cosmo's version might read marginally differently depending on surrounding palette colors. Since 915 sits on the border between red and purple families, small shifts in that balance can affect how the color reads in palette context. For backstitch applications and standalone fill work where the specific red-plum balance isn't critical, Cosmo 261 is a workable substitute in most finished designs.
