DMC 825 to J&P Coats: Thread Conversion

J&P Coats 7181 is a close match for DMC 825 Dark Blue. The close rating reflects a minor difference in the blue's specific neutral-gray character, which may be more or less visible depending on your lighting and fabric. For designs where 825 is doing heavy-lifting as a primary dark blue fill — ocean scenes, sky gradients, large denim areas in portrait work — comparing J&P Coats 7181 on a test swatch before committing is recommended. The neutral-gray quality that makes DMC 825 so universally useful may be slightly different in the J&P Coats version; if the substitute reads cooler or more teal than the DMC original, the color family relationship with lighter blues in your design will shift accordingly. Dye lot consistency across multiple skeins is worth checking if your project requires a larger quantity. For projects sourced entirely in J&P Coats, 7181 serves the same workhorse utility-dark-blue function that DMC 825 provides in the DMC line.
