Bucket List #8 Make a Hidden Book

I have always loved a good mystery and as a kid things like hidden books, secret bookcase doors, forgotten rooms or passage ways, and treasure maps tickled my imagination. So when it came to making a bucket list of things I always wanted to do.....

Can you guess which one it is?

I found this outdated and abused book at the donation center at our local library. This project cost me a dollar for the book, a razorblade, and part of an afternoon. The child in me is very pleased with how it came out.
