DMC 161 to Cosmo: Thread Conversion

Cosmo 153 is a close match in the grey-blue range. Cosmo's softer thread construction produces a slightly flatter stitch at this medium-dark value, which suits the dense shadow-side fills that 161 typically handles in stone, denim, and maritime applications. The grey component must be present — a substitute that reads purely as medium-dark blue loses the atmospheric, weathered quality that distinguishes grey-blues from the cleaner blue families. Verify on your fabric before committing.
