Writing board books is a little like math or music for me. I love it! I love gazing at the entire story in my head, and then pouring it into just a few hundred chosen words. And saying the words out loud, nodding along, hitting a pencil to the desk, listening for beat and tripping tongue moments, pressing all the meaning and metaphor and allusion into those few, chosen words. Saint stories are fertile ground for this musical math. Sometimes only a few words of story are known, sometimes there are many and it is a greater labor to fit them into the tiny book. I love doing it.
