Part of the purpose of Storyweaving is to communicate the underlying dramatic structure or message of a story. The other part is to make that process of communication as interesting and/or effective as possible. In addition, the manner in which the structure is expressed can have a great impact on how the audience receives the message which extends far beyond simply understanding the message.
Our first job then is the somewhat mundane task of describing how a structure can been communicated through exposition. Once we have laid this foundation, we can cut ourselves free to consider the enjoyable aspects of using weaving techniques to build suspense, create comedy, shock an audience, and generally have a good time putting the frosting on the cake.
