Brian,You are right. I have been prepping them running the thread on my beeswax block and pulling it over my fingers to work it in. That may be part of what is seen but the flame would melt it in better. All of which may work against absorption of the glue into the fibers. I'll give it a try. Thanks.. Rich
What sequence would you recommend?
Candle to remove thread fuzz before running it over the beeswax and rubbing it in?
Beeswax and finger rub before the candle flame?
Or another approach. . . .
I also think that the textured striations on the small tweezer points pull up some fibers which were tight before securing the knot.
