Step 1: The First 20 Pages
To make your secret “book safe” as convincing AND easy-to-access as possible, we recommend that you leave the first 20 pages alone, then glue the next 10 pages together, to serve as a lid of sorts to your secret compartment.
Simply slather each page from 22-29 with your adhesive of choice and stick them together.
Remember to work as cleanly as possible to avoid excess glue and drips.
