A Double Hinge book is just like a normal book, except it opens in two places. There are a lot of different shapes you can use for a double hinge book - almost anything that opens or unfolds. You can make a bat, a toy box, or even a clamshell!
The things you'll need to make a double hinge book are:
2 small pieces of construction paper or card stock
1 large piece of construction paper or card stock (this piece needs to be big enough to hold the two small pieces)
This pattern shows how to make a book that looks like a bat!
