[expand]The lattice walls (khana) were collapsible framework of wooden poles bound with leather strips at crossing points. Each lattice section consisted of perhaps twenty to forty poles arranged in diamond pattern, their crossing points allowing expansion (to enlarge yurt diameter) or compression (for transport and storage). The sections connected end-to-end forming continuous circular wall, the number of sections determining yurt size—small family yurt might use four sections, wealthy household’s yurt could employ eight or more sections creating spacious interior.
The pole selection required straight-grained hardwood—willow, poplar, or similar species—that combined flexibility with strength. The poles were split rather than carved to preserve grain continuity, reducing breakage risk during flexing. The thickness was substantial enough to resist bending under felt covering’s weight yet thin enough to remain lightweight and flexible. The length determined yurt’s wall height—longer poles created taller walls, shorter poles produced lower profile more resistant to wind but with less interior headroom.
The binding method used leather strips rather than rigid connections, allowing lattice movement during assembly and disassembly. The leather wrapped around poles at crossing points, tied securely but not so tight that poles couldn’t slide slightly during expansion. This flexibility was essential—rigid connections would prevent lattice adjustment, causing either loose walls (if set for maximum expansion) or impossible assembly (if set for minimum compression). The leather bindings required periodic maintenance—re-oiling to prevent drying and cracking, replacement when wear became excessive.
The assembly began with expanding single lattice section to approximate desired dimensions, standing it vertically, then adding additional sections end-to-end forming gradually curving wall. The sections connected through overlapping end poles bound temporarily with cord, creating continuous circular framework. The process required at least two people—one holding previously assembled sections while second added next section, coordinating movements to maintain circular shape without allowing structure to collapse. The experienced family could complete lattice assembly in perhaps thirty minutes, their practiced movements efficient and confident.
