Don: I wish I had a more interesting or profound answer to this question, but I learned about Horton through a writing partner, Chris Barton. I started researching Horton on that same day. I knew from day one that Horton's story would be loved by readers, but because of my heavy illustration schedule, I didn't know when I'd find time to write it. And then I had this fear that someone else might publish the story before I had a chance to start writing, so I found the time. Several years and many, many revisions later, the book was acquired by Peachtree Publishers.
Don: Initially I wanted to illustrate "Poet" digitally. I'd just purchased a Cintiq, and I was anxious to put it to use. I did all of the line work on my Cintiq, but I think it freaked out my art director, who had another look in mind. She loved my hand drawn artwork, as done in the book "Hope's Gift," so I decided to use the same medium, acrylic watercolor washes and ink (Micron) lines on watercolor paper. Acrylic dries hard and allows for layering without disturbing under painting. And I used colored pencil in places. I also wanted to find a way to include Horton's poetry, since I'd not included any in the text (intentionally). So I hand lettered portions of his poetry and worked them into the illustrations using Photoshop. I did eventually get to put that Cintiq to work on my following book, "Whoosh!"
Don: Balancing creative time with travel can be a challenge. To help, I recently purchased a Surface Pro 4. It's a tablet that allow me to sketch on it using Photoshop or Manga Studio. I completely sketched and laid out my last two books on it. It's not great for creating final art, but totally saved me with my last two books. I also have a great booking agent who helps with the details of travel, so that I can spend that time in creative mode. I take it one day at a time.
I have five more books under contract, and one to be announced soon. Most of them are nonfiction and involve little-known historical figures. I'm especially excited about an opportunity to work with Eloise Greenfield. That will be so cool!
