Kite-Runners of the Two-Cast Loom-Bridge — an age when a river-market weaving quarter is built by the fold-carpenters so that its one great warp-bridge, a taut span of dressed silk threads stretched between two working looms, does not carry a shuttle from the near loom to the far loom across the room but folds the span back through itself: the identical rank of warp-threads a Runner is dashing ACROSS toward the far loom she can see clacking at the room's end is, in the same silk in the same instant, already delivering her BACK onto the near loom she just sprang from behind her, so the far shed ahead is the near shed behind and the warp-bridge has no other end, only the seam where forward is return — and the Kite-Runners have learned the loom-bridge cannot be walked across, only crossed at the fold in one committed running stride over the singing threads, one bare foot pushing off a taut warp-beam that flings her toward the far loom while that same push lands her back on the near loom's breast-beam driving her toward the fold again, caught mid-dash over the vibrating silk between two ends of the same weaving before the two-cast loom-bridge decides which loom the day's work will spill her onto
