DMC 3031 to Sullivans: Thread Conversion

Sullivans 45323 is a close match in the very dark mocha brown range. Very dark threads like this one are where brand differences tend to show up most clearly in finished work, as the deep color makes any temperature variation more apparent against surrounding lighter values. For full-coverage pieces where DMC 3031 fills significant areas alongside lighter mocha-family values, testing Sullivans 45323 in context before committing is the safest approach. Coverage density should be verified before use in large dark shadow areas.
