Query: Some good-looking folds, but incomprehensible instructions.

I've been into napkin-folding for over 35 years, since first encountering some brief folds in the Vincent & Mary Price Cookbook, "Treasury of Great Recipes." While I find at least a couple of the folds in "Napkin Folding" compelling (not a very good percentage), they also seem to be the ones with the least comprehensible instructions. Ginders is fine when he's writing conventional text, but it seems like he's bent over backwards to make his explanations brief...to the point of uselessness.
