DMC 121 to Cosmo: Thread Conversion

Cosmo 2591 is a close match in the medium blue family. As a solid thread, it delivers reliable, even coverage in the Delft blue range — good for Scandinavian and modern design applications where clean, consistent color is the goal, but missing the handmade variability that makes DMC 121 work so well for historic ceramic-inspired designs. For forget-me-not clusters and hydrangea designs where the subtle petal-to-petal variation adds realism, look within Cosmo's variegated range for a closer match to the original's effect.
