Aso oke is woven by men on narrow horizontal treadle looms, in strips four inches wide for a robe and up to eighteen for a woman's wrapper, then sewn edge to edge into a finished cloth. Etu, the indigo type, is dipped until it reads almost black, broken only by warp stripes a single thread wide.

This system builds every layout the same way: unequal narrow columns butted together with the seam left visible, magenta alaari entering only as stripe and weft-float brocade, sanyan beige carrying the section bands. No gaps, no shadows — separation is a seam.
