This is a trick that will make the half rosette unnecessary. It works for all kind of sticks that need securing, if only they have a hole in each end.
Myself, I find it indispensable when securing lease sticks.
This is how to do it:
Cut a length of rug warp, seine twine or the like. It should be double the length of the stick in question, plus some extra (some 6 inches is enough).
