I then print out a bunch of thumbnail sized squares/rectangles to represent what the book page layout will be when the book is open.
The line in the middle of the rectangle represents the page break due to the binding so that I can be wary of it when I start to draw out what the illustrations will be like.
After lunch they went outside and found Cynthia’s dog, he was all dirty from rolling around in the grass.“I think my dog is going to need a bath,” Cynthia said.“I can help with that,” Clive volunteered. So she gathered some soap and towels and washed her dog while Clive wet him down with his raindrops.
And that's how I storyboard my book. ^_^
