Traditional Boie’nen rattan plaiting technique
A skilled weaving method from the Boie’nen culture, using a single narrow strip of rattan to create a tight, expandable diamond-lattice (herringbone-plaid) cinch ring.
This self-tightening binder is primarily used to secure bundles of coconut palm midribs (petioles) into traditional brooms (walis tingting). The plaiting forms a contractible tubular ring that cinches mechanically when pulled and shrinks further as the rattan dries, creating a durable, knotless, and load-strengthening hold.
While visually intricate, the herringbone-plaid pattern serves a functional purpose — enabling radial contraction and friction grip. Though sometimes adapted for edging bamboo mats or lightweight fixtures, its core traditional use is in broom-making, where it exemplifies sustainable, zero-waste fastening design.
