Today I've spent a little while looking at the plots of all the fairytales, and breaking them down into 8-point plots. This will give me an idea of which characters and other elements I need to illustrate so that I can move on to decide which animals to use for which characters. I've also made a few notes on ways that the stories could overlap with each other if I later come to combine them all together. These are just ideas at the moment and I won't be taking them any further for now, but I wanted to be sure to keep a note of them for later reference.
Now that I know which characters I'm using I am going to continue researching the symbolism of various animals in order to assign them to the characters and begin illustrating them.
