how to make a secret hollow book
What you’ll need:
• Hardcover book
• Plastic wrap
• Box Cutter
Consider where you are going to start cutting the pages. Leave out the first quarter of the book free for allowance. Wrap both covers with plastic wrap or a plastic bag, including the first quarter of the book, to keep it from getting glued.
Close the book and apply an ample amount of glue mixed with water around the edges. Coat the edges thoroughly. Put something heavy on top of the book and let it dry for at least 12 hours.
When it’s dry, it’s time to start cutting. Measure the size and the shape you want, and make sure to leave a margin—at least half an inch. Carefully start carving around the edge with your box cutter. Leave several pages at the back of the book uncut, for structural support.
