Very useful tutorial! (Love the Good Eats reference as well!)
Do you have a source for the taffy-pull method? I do historical re-creation and would like to be able to document everything to the satisfaction of the most anal judges. Pine trees grow around here (Northeast Ohio, USA, near the Lake Erie shore), so I have a ready source of rosin.
You mentioned bristles. I've been looking for boar bristle to experiment with ever since I read about the technique in the Stohlman book a few decades ago. Source? Please?
