Here is what I do. Remember this is how I do it, not the end all cure.
I start just as you describe. The only difference is I leave the tag ends of the thread long. Long enough to grab and pull on after the trim band is wrapped. After the trim band is wrapped, I use my fingernail to sung the trim wrap against the main wrap. I then grab the long ends of the trim wrap ant pull them very snug. You will learn quickly how much pressure the thread will take. after snuging up the wrap, I trim the tag ends to 1/2" long. After all the guides are wrapped, I apply a thinned coat of finish, leaving the tag ends exposed. After the first coat dries, I go back with a SHARP knife and trim the tag ends and any other imperfections in the wrap, then apply the final coat(s) of finish.

I hope this helps...
