Ideas mostly come from the work itself. Often when I'm drawing, the words will be bouncing around in my head, and when I'm writing, ideas about the drawing happen.

Often they do go back and forth the whole way, and I don't know until the very end what the last line of the book is going to be. That was true here - the very last line of the book was the last thing that happened.

It would look like a notebook with dividers, and there'd be different subjects and things [preschoolers] could do, so that they could feel like they were going to school also.

I felt ten years old and a thousand years old, but I didn't know how to be my own age. I had never felt that way before, but now I feel like that a lot.

I started thinking about [ what book is going to go next] when I was working on As Easy as Falling Off the Face of the Earth.

I do love that discovery of when you're trying to figure out how to make something work, and it happens in a way that you didn't predict.

A long time ago, I had an idea to make a book for preschoolers who had older siblings who were going to school.
