A very good way to draft a children's book is to place it all on Google Docs first. Google Docs is an online way of storing, working on and then sharing your work, whether that is a book draft, a document or a web page. You can type in and save your text, upload illustrations and images, store online web page resources and even share these for marking purposes with your assignment teachers. Of course, at the end of it all, you can print off the pages to form them up into a book. All the usual tools are there such as word count, spell checker, margins, insert tables and all the other usual word processor tools. You can choose privacy too, if you prefer, as you dont have to share the files or pages until you have proofed your assignment.
