There have been several versions of the story since it was originally created. Natalie created the original story and drew out storyboards for the sequence of pictures that would be used along with text in the book. The pictures were developed in color for a second round, then standardized and set with text for page layouts.
This is what the first three drafts looked like:
Marisa was able to take these storyboards and begin work on transforming the art for the book. She started by creating concepts of the book cover and inset for the published book.
At this point we still don’t know what publisher we’ll be working with, and have only estimated the dimensions and material for the book.
The next step was to transform Natalie’s pictures into pages, with a better idea of the number of pages that will be in the book.
