I was really fretting over it, and then suddenly, I saw the light. Just treat it as a 'Sketch Book' - go with the 'what if' idea. Use it as a way to explore other techniques, just be loose with it! Phew!
So, I have made a start.
My theme is Memories (we could choose our own theme) which is vague enough to give me scope to 'fly' (here's hoping) and my first activity was to do a bit of a brainstorm on the word 'Memories'.
There is lots here to work with, and to take me on my twelve month journey.
Keep watching as more unfolds!
