These books are little note books, the smaller the better. Pages are slapped with paint, stenciled, stitched, photo transferred images, lots of modeling paste plus lots more techniques, just feel free to let go and have fun.
Some books are just individual pages worked on and then bound together to make a fat book. The great thing about these is that even when you think they're finished they're not, you can just carry on, then where do you stop !! Try it.
