I emailed Rebecca about how the artwork is done and here is her reply: The art is created by my cutting pieces of brown paper and pasting them to a white sheet 8.5x11. I do not draw them first, I just cut. Then my father scans them into FreehandMX (which is obsolete but we keep using it) they are then black, so I color them on screen, assemble the pieces (which is sometimes a surprise since I only envision with my scissors) Then my father and I lay out the pages together. He usually designs the jackets.
Thanks to Rebecca for replying to my question. That informal kind of communication is one thing that has been a pleasant surprise with this blog. When I don't find enough information, I usually can find an email for the author or illustrator and VIOLA! more info!
This version of the ant and the grasshopper would go well with a second or third grade folklore unit. It's a new take on an old tale, so it would help get the kids thinking about stories and the deeper meaning they have.
