See if this helps!
Hi Gloria. My name is Cindy. Start by creating a template. Then draw a series of rectangles on a piece of paper (as if you would make a comic strip). Draw a series of scenes in the rectangles. Next add your script. Write the dialogue that corresponds to the scene in the rectangle. Continue until your story is complete. Gloria, a good storyboard serves two main functions: planning and communication. Good luck.
What Cindy says, my would be movie director grandson and artist husband do this.
Gloria: maybe this will help
