Carol Barton is a paper engineer from Washington. I recall a wonderful dinner and a lot of discussion about pop-ups (both she and my mother are known as ‘The Pop-Up Lady’). She makes lovely artist books as well.
I love this tunnel book! With a tunnel book, rather than flipping pages, the pages (or layers) expand like an accordion. Most tunnel books are viewed through a small hole on the front. Tunnel books have a very intimate feeling… like looking into another world.
