Some people are using old books to create works of art, including sculptures. They can change the shape of a hardcover book so it becomes 3D. The resulting sculpture has not only a length and width, but depth. The process can be very simple, and the result is often beautiful. 

There are many kinds of book folding. Artists fold, bend, and sometimes, cut a book's pages while keeping them together. The art works can be hung on a wall or placed on a table. "They look impressive on the wall," says writer Candice Caldwell. "A group of six of these on the wall together can look really beautiful, and they're just really simple folds."

In 2003, Caldwell started making clocks from old books when she saw plans for a simple book-folding project in a do-it-yourself magazine. She has since taught several friends and her mother how to create wall from books.

Caldwell operates a blog. She writes about reshaping everyday objects like books for uses other than what they were designed for.

Clare Grey has written a book called Folded Book Art. He says book folding is easy. From his home in England, he told the Associated Press by email that "it looks as if it is complex and unachievable, but it is really easy to do. You just don't tell anyone how easy it is and they will be amazed at your creations.

Grey began making art from book pages several years when he saw pictures of folded books at the website Pinterest. com. He also watched some videos on YouTube that tell how to create art from books. 

Grey suggests folding cooking recipe and photography books. He says that "If it's really visual and really colorful when you start to fold them, you get a whole new look on the wall."
