Here are links to PDFs of some materials for introducing Hexagon Squares to newbies. (That's new to hexagons, not new dancers!) They're formatted for 8.5x11 paper (mostly 2 diagrams to a page). Click the thumbnail to view/download the PDF. (Yeah, the couples are half sashayed in a bunch of them. Sorry about that :-( But you have chosen reasonably competent DBD dancers to start with, haven't you?)
Happy teaching!
Of course, Clark Baker's doc and the animations it contains links to is the central "must-read" document.
