To get the end of the serving wound tight and reliably strong I usually loop about 9-15 times under a short strand of string and through a loop of that same string. Then I yank the loop (from the opposite end of the loop itself in a quick motion) and serving end back under with my fingers. Once in a while pliers makes it easier but it is usually not necessary. Once it’s under and back through I cut the ends so that they are flush with the rest of the serving which is wrapped around the string and that’s where I use a drop of Duco Cement.
The photo might make for more questions than I want to answer.
