On a simple frame loom, a shed stick is used to lift every other warp
thread — first one half of the threads, then the other half. In rigid heddle
weaving, warp threads pass alternately through slots and holes in a heddle. Raising it lifts half the threads (the ones in the holes), lowering it raises
the other half (in the slots). The shuttle carries the weft back and forth.
