DMC 91 to Cosmo: Thread Conversion

Cosmo 2640 is a close match for DMC 91 Variegated Orchid. Cosmo's variegated threads have a solid reputation in the stitching community, and 2640 covers the purple-orchid family territory comparably. The close rating signals that the color family matches rather than the exact sequence — your finished piece will look related to but not identical to one worked in DMC 91. For orchid and lavender floral designs where the variegated effect matters more than specific brand accuracy, Cosmo 2640 is a workable choice.
