I know. I was thinking of going the coloured pencil route. Of course, that means I have to go out and buy coloured pencils at the same time as the new notebook and the glue and the varnish and... yeah. This book may end up being a bit expensive. ;)

What size/type of notebook do you use, out of curiosity? I've always favoured the spiral-bound type with about 100 pages (standard 8.5 x 11), but I think it might not work for a collage cover.
