The witral is an upright loom — four stakes, a rectangular frame — and its name means "to be vertical." On it the makuñ, a lonko's poncho, is built warp by warp. From across a room it is black and white. Up close it is the deepest indigo and a warm beige, because black carries the depth of blue and is hard to make, and white is divine absence, so a beige white stands in its place.

This system takes that reading literally. Figures are stepped, never smoothed: every diagonal is a stack of whole squares, because supplementary-warp figuring cannot do otherwise. The wenufoye — the stepped cross — sits centred and load-bearing, mirrored across both halves. Corners are square. Nothing casts a shadow; the weave lies flat.
