DMC 813 to Cosmo: Thread Conversion

Cosmo 140 is a close match for DMC 813 Light Blue. Light blue is one of the more forgiving colors for close-rated substitution because it's a common, clearly-defined color type without complex undertone requirements. For large sky fill areas where 813 is used in significant quantity, checking dye lot consistency within the Cosmo 140 you purchase is still worthwhile — even well-matched light blues can show subtle batch variation across large stitched areas.
