First choose what book(s) you want a miniature version of.
Bring both the front and back coverings up so it looks like so and take a picture. Make sure you crop out everything but the book.
Print the pictures on the smallest setting your computer has and cut them out.
On a very soft and thin chip of wood mark where to cut.
If making a necklace now is the time to glue on a i-pin.
Spread glue allover the wood chip and place book cover on it.
After the glue dries you toys have a new book!
Or you have a new necklace.
