I'm considering building something akin to a bamboo pergola and tying it together with a rope. What would be the best method for tying its 'corners' where three poles meet?
From the Wikipedia article on lashing and browsing other sources it appears that the likely choices for tying such 'corners' together are either to use square lashing twice or tripod lashing, but probably the first.
However, I came across images of bamboo scaffolds that to my untrained in lashing patterns eye seem to show a single binding at the 'corners'. Could that be the case?
