Starting with an underlying structure of corrugated cardboard to work from, and a few reference pictures of horses's heads, I slowly built it up with more card and white glue until I had a good base to work from. From there it was just layering up the book pages with glue and water and waiting for it to dry. As for it's feasibility as a material for stop motion - sets maybe in limited circumstances, but it's a bit too flexible to be relied upon. That's about it?
