DMC 310 to Cosmo: Thread Conversion

Cosmo 600 is listed as a close match. In practice, Cosmo's black is virtually identical in color to DMC 310, but the thread itself has a different hand — silkier and slightly thinner, so your coverage may vary. You may need to use slightly more tension or add an extra strand when substituting Cosmo for DMC on the same project to achieve equivalent coverage density. The close rating reflects these practical differences rather than a meaningful color difference.
