DMC 208 to Cosmo: Thread Conversion

Cosmo 278 is a close match in the very dark lavender range. Cosmo's softer thread construction produces a flatter stitch surface that can affect how the deep lavender color reads — flatter stitches may appear fractionally lighter than DMC's more textured cross at this dark value. For iris petal shading and wisteria shadow areas where 208 provides the deepest shadow, test Cosmo 278 on your fabric at full stitch density to confirm it delivers the necessary depth before committing to a large shaded fill.
