STEP 3: HOLLOW OUT YOUR BOOK
Open the book and mark the edges of your hollow. They should be at least 1/2″ from the edge of the pages.
Pro Tip: Measure how deep you need to drill so that you don’t hit the book cover, then put a piece of painter’s tape around the drill bit at that depth!
If you have a drill, use it to make holes along the edge of your inner chamber. These holes will allow you to keep your cuts shorter, giving more control over the knife (always a plus) and helping the corners detach.
