DMC 152 to Cosmo: Thread Conversion

Cosmo 122 is a close match in the warm shell pink range, covering the medium-light peach-pink territory with Cosmo's characteristic softer hand and slightly flatter stitch surface. The shade should read as a warm, peachy-pink medium light — confirm it sits in the correct shell pink territory with orange-pink undertones rather than veering cool, grey, or mauve before purchasing for a project where undertone fidelity matters. Cosmo's softer thread construction produces a slightly flatter stitch surface that suits the gentle, delicate quality of 152 very well — particularly for small, fine-scale motifs like bootie borders, tiny flower heads, and stork details in birth samplers where a softer, more refined stitch appearance is desirable. The flat stitch profile integrates smoothly into the fabric texture, giving small motifs a clean, precise look without any raised or rough quality. The warm, peachy-pink shell character should be preserved in Cosmo's version. Verify with a test swatch on your project fabric that the undertone sits correctly among your other shell pink threads — in particular alongside DMC 224 and DMC 223 if you're building a full shell pink gradient, since the warmth should remain consistent throughout the family without any individual thread appearing noticeably different.
