Lindsey,
From “Knights Modern Seamanship” 10th edition (the only US Seamanship manual I have)
Naval Terms and Definitions: " Fox - Two yarns hand twisted or a single yarn twisted against its natural lay; used for light seizings" (hence the twisting tool named a ‘foxer’)
No mention of nettles in there - But from Nares Seamanship (UK) 1897
Foxes - “Short yarns laid up by hand - laid up left handed”.
Nettle Stuff - “2 or 3 left handed yarns laid up right handed” (used as clew lines from the ring to the hammock - hence the name ‘nettles’)
I use the figure of 8 twist over the thumb and little finger a lot (especially when whipping/serving the Pilot Cutter handrails) and was taught how to do that in my naval training at HMS Ganges - not with line, but morse and murray code paper tape! - so that it would feed through the autoheads without twisting and snagging. No name was given as far as I can remember.
