I like this story a lot, and so does he. It has simple illustrations based off of photographs of a quilt that tell a story. It is translated from German though, so it reads a bit awkwardly at times.
One of his favorite lines from the story is, "Brushes and colors are set to go, to paint the beetles see how they glow." He runs around quoting it all the time. He went through a phase this spring always talking about "paint the beetles!"
He really liked painting the rocks.
