Book Art by Kylie Stillman.

We have seen quite a few works of art using books as medium, but Kylie Stillman's work is quite distinctive. She uses books as if it was a block of marble, but she engraves rather than sculpts. Her work involves the handcrafted removal of pages of books to make a hollow space and creating beautiful works of art.
