Thanks to Diane's correction I've now found lots on the technique of Sprang. There's an nice tutorial by Kirsten aka "thesojourningspinner" here on you-tube... how to do sprang also circular warp sprang and holes in sprang, then larger holes for hairnets or bags and interlaced sprang. Finally, lots of interesting possibilities for springy sprang... collapsible sprang.
ooo and sprang intermixed with weaving! Even clothes
