I've discovered that organising my characters for a new book, is a considerable pain. They are now on file cards. I can pick out the fictional people and remember what they are like (from my notes)& how they react. I can also add notes to these file cards if my creatures have been through an experience that has affected them in some way. It's a good way to weave the threads of a complex plot. The scenes can be put on cards in a similiar way. This may seem rather an archaic way of arranging things in this age of the computer file. I do find the physicality of bits of card board helps creative thought. Staring at a computer screen for too long can become painful. I do think more clearly using this for basic plot and character structure. Try it; what do you think?
