DMC 3371 to Cosmo: Thread Conversion

Cosmo 2550 is a close match for DMC 3371. Cosmo's equivalent may appear very slightly more brown and less black than the DMC version — the near-black depth of the original is the quality most likely to shift. If you're using Black Brown specifically for its near-black outlining properties (the warmth being secondary to the defining darkness), check that Cosmo 2550 reads as dark enough for your purposes on your specific fabric before committing to a project's worth of backstitching. For designs where warmth is the primary concern and absolute darkness is secondary, the close match works well.
