Learners will be using whatever method is most comfortable for them for sharing stories.  This may be drawing, writing or some combination of those (comic or graphic novel style, text with illustrations, etc.).  Some learners may enjoy posting recordings of themselves talking about their ideas, presenting their ideas as a puppet show, or responding to prompts as a character.  This is very welcome but not expected or required.  Some learners enjoy using building blocks or bricks or other materials you may have at home to build models of the Unicorn Library and other locations in the imaginary world at the end of the rainbow.
