DMC 545 to Sullivans: Thread Conversion

Sullivans 45203 is a close match for DMC 545 Light Wedgwood Blue. Since all four listed substitutes for this shade carry close rather than exact ratings, the practical advice is the same across the board: compare in person on your actual fabric, and prioritize the grey-blue equilibrium over either component alone. A substitute that reads as clearly blue (Wedgwood family) or clearly grey (antique blue family) has missed the in-between quality that makes 545 distinct and useful for vein shadow work in portraiture and smoky tile-pattern fills.
