Thanks much for the further thoughts cloddopper & Alex_.
Have used the threaded-wire method so far, but (with other tasks mounting up) I have made a few "temporary" simple hog-ringed overlaps. Overall, my Field-1 fence is rabbit/deer proof (touch wood), but the slightly loose hog-ringed laps are not to my liking despite it being a very quick method.
Fencing of Field-2 beckons and the experiments continue! I might give twisted wire a go after-all (thanks Alex_), but I'm not sure, cloddopper, I fully grasp your method - could you run that past me again please?
