Not sure what it's called, but we make the same knot that the baler knotter makes to tie balls together. Hold the 2 twines together, make a loop, and pass the ends through the loop, trim to about 1 inch. If you cut the ends too short (makes no difference in the knot) the twine will simply pull apart.
(for tying line to a hook) 1. Thread the line through the eye of the hook, then make 5 to 7 wraps around the line with the loose end. 2. Thread the loose end of the line through the loop closest to the eye, then back around inside the loose section of line. 3. Pull both ends of the line until tight.
