A Chilkat robe is a clan crest translated into thread. The warp is shredded cedar bark twisted inside mountain-goat wool; the weft is dyed goat wool; a single robe can take a year and carry up to 160 moving braid strands down its face. The documented palette is narrow — black, white, yellow, blue — with yellow and black doing most of the work.

This system takes the robe literally. The page is the hemlock-and-iron black of the formline field. Wolf-lichen yellow fills. Copper-oxide blue-green supports and never leads. Undyed wool stays a small inner field, never the ground. Every shape is outlined, and every curve steps, because a woven curve cannot be a true arc.
