I’m building a hidden compartment in a book. Just for fun, since now everyone knows I’m doing it.
I like the write-up from the Art of Manliness. I’m not really using it as a secure place to put things, but more to have neat and interesting things to find. I’ll going to put a key in there and a clue. That will lead to a secret room with a safe in it. And there will be a map to a treasure.
Then sell the house and leave the book somewhere.
Really, I just like making projects.
