Thank you for the link, QuiltingVagabond! I was thinking of those half-chevrons, and avoiding drawing lines by using the Simple Folded Corners ruler. I suspect that I will then have to make the little HSTs separately, which I don't mind. I don't like the idea of guesswork and scant seams to make the other method work.
I wonder if those making the separate HSTs will need extra green yardage, if Bonnie calculated the yardage with her bonus buddy method in mind.
edit
I don't really get what the Bonus Buddy Ruler is for; not really understanding her photos and text this time. I'll try reading it again.
