DMC 3828 to Madeira: Thread Conversion

Madeira 2103 is a close match for DMC 3828 that is workable in most hazelnut-brown applications. The warm-medium-brown character is generally well-represented, though some dye lots can sit fractionally more golden or fractionally more neutral than the DMC original. For gradient sequences where 3828's bridge position between golden and dark-neutral browns matters, a comparison swatch under daylight ensures the Madeira version sits at the right value before committing to fills. The exact Anchor match is preferable for gradient-critical work.
