I used the stamp sets "Around the Block" and "Flower Pot" both from Close to My Heart. The ink and paper is from Stampin' Up, Not Quite Navy, Rose Red, Creamy Caramel and Boredering Blue!
To create the whale I cut a rectangle and used the corner rounder, then just manually cut the back end and hand drew the face and flipper.
The inside of the card reads: "Thinking of you... please know that I care." and is from Stampin Ups "Thoughts & Prayers" stamp set.
Edit to add a YouTube link with a relevant clip from the movie which is based on the book.
