DMC 121 to Anchor: Thread Conversion

Anchor 1210 is a close match as a solid medium blue in the Delft range. The handpainted, organic quality that makes DMC 121 so effective for ceramic-inspired designs is inherently lost with a solid substitute — consistent color coverage reads as uniform where the variegated original suggests the variable brush stroke of a human potter. For Delftware tile designs, consider whether the solid's cleaner appearance suits your aesthetic goals. For small motifs or borders where the variegation wouldn't have been noticeable, Anchor 1210 is a reliable stand-in.
