Write a plan for your story, going into detail on what your characters will do, what will happen in your story and how this will develop.
Draw a series of frames on paper with a pencil and ruler. Make the frames a decent size, such as 10-by-10 centimeters, but change the sizes to fit in with the dialogue and artwork.
Write your story as a script but break it down into sections and specify which sections of dialogue are going to go into each frame.
Sketch the artwork from your story into each frame, adjusting the frames to work with the story so none of the important parts of the story are missing.
Draw the outline of the artwork in each frame with pen. Add color using inks or colored pencils to each of your frames.
Proofread your storyboard and read through your story to see if there is anything you can improve upon. Show your storyboard to a friend or work colleague to get their feedback.
