The Orari River is not far from my home here in South Canterbury, New Zealand. It flows from its source in the Four Peaks mountain range, and past the towns of Geraldine and Orari on its way out to sea east of Temuka. When it is in flood, the current is much like the stitch pattern on the instep of this sock, with the mini cables depicting where the edges of the river are trying to find their new path.
