DIY Book Safe to Hide Your Coolest Valuables

Learn how to make a DIY book safe using an old book and Mod Podge! It’s the perfect place to hide your valuables on a bookshelf.

Skills Required: Beginner. You’re going to be using a craft knife to cut a book and then Mod Podging it. It helps to have previous experience with crafting, but this is sa project anyone can done.

DIY book safe

When I was little, I loved Nancy Drew mysteries. My mom had nearly the whole set, and I read them all.

This book safe is just the kind of thing that would have been in one of those mysteries! I firmly believe that solving a mystery needs to involve a book safe at one point or another, don’t you?

I personally would have loved one of these when I was younger. This is such a great craft for teens! Of course my valuables consisted of junk jewelry and about $.83 in change, but you have to start somewhere.

What was once a love of Nancy Drew has turned into a full blown adult obsession with true crime. I love mysteries. I love twists and turns. I love hidden stuff in bookcases. I think you see where I’m going with this.

Due to both my past and current obsessions with crime and mysteries, I’m all about hiding things in plain sight. It intrigues me now just as it would have when I was young. I’m going to show you how to make a book safe the easiest way possible.

Tips for Making a Book Safe

Before we get started I’ve got a few tips for you; I suggest you read these especially if you are a beginning crafter. Otherwise, please scroll down to get the how-to.

Choosing a Book

There are a few things you need to take into consideration when selecting a tome for your safe. The first thing is that it needs to be thick enough to support cutting into the pages and providing a recessed area to store your goodies.

My book was 1 1/2″ deep, but you can go as deep as you like (that’s what she said!). But seriously, you might want to consider first what you are going to be storing in the safe before you select your book.

There’s nothing more disappointing than doing a project and realizing it doesn’t work to fit your needs. Any depth of book is fine – the technique is the same regardless.

Second thing I wanted to address: I know some people get up in arms about cutting books. There are a lot of places to get old books that would otherwise be thrown away (check out Freecycle).

You can also visit the library and ask them about books they are planning on trashing/recycling. That way you are cutting up an item that would go into the garbage anyway.

Razor Blade or Craft Knife

I used a craft knife for this project, but you can also use a razor blade with a handle. The most important thing: make sure your blade is very sharp! You’re going to be doing a lot of cutting, so you’ll probably want a new blade to make life easier.

Mod Podge to Use

We used the Hard Coat formula for this DIY book safe but that’s only because it’s what we had available. Hard Coat has a Satin finish. You could use Gloss, Matte, or Satin too. Matte will likely most closely match the finish of the pages, but honestly it doesn’t matter.

Gather These Supplies

  • Old book
  • Mod Podge Hard Coat
  • Paintbrush
  • Clamps or clothespins
  • Painter’s tape
  • Craft knife
  • Ruler

Tips and Thoughts for This Project

Technically I suppose you could open the cover and there is the safe right there, but I wanted there to be a few pages before the recess. Just adds to the mystery, I guess.

Clamping the pages while cutting is not required, but if you can clamp them down (or even tape with painter’s tape, which is removable), you’ll keep the cuts more even.

Materials

Tools

  • Craft knife

  • Pen or pencil
  • Paintbrush

Instructions

  1. Decide how deep you would like your safe to be. I mentioned there was about 1 1/2" inches worth of pages in my book. I held about 1/4" worth of pages at the front of the book and then 1/4" worth of pages at the back to be the bottom.Hand flipping the book pages
  2. Clip approximately 1/4" of pages to the front cover of the book using clothespins or clamps.Clip the book open with clothespins
  3. Using a ruler and pen or pencil, draw a rectangle that will be used as your cutting template. Leave at least 1/2" around all sides that will serve as the edges.Drawing a rectangle shape to cut using a ruler and pen
  4. Clamp the pages down that you'll be cutting.Clamps holding the book pages down
  5. Using the ruler and craft knife, make cuts on the lines you drew. Go as deep as the knife will let you go; don't try to do too many pages at once.Using a craft knife to cut into the book pages
  6. You'll be cutting out 10 - 20 pages at a time with a craft knife. Once you've cut out several pages worth, remove them.Cutting and removing book pages
  7. Before flipping the pages of your book safe to make additional cuts, use the previous cuts as a template - draw another rectangle with your pen just inside the rectangle.Tracing the previously cut portion of the book with a pen
  8. Flip the pages you've already cut and reclamp the book. Use the ruler and craft knife to cut additional pages. Complete this process over and over. Repeat cutting and removing pages until the recess is as deep as you would like, leaving at least 1/4" of pages at the back of the book.Additional pages cut out of the book safe
  9. To prevent the Mod Podge from seeping into the back of the book, use painter's tape to tape down the back cover. Hold up the front pages of the book in front of the recessed portion.Securing the back cover of the book to prevent Mod Podge seepage
  10. Apply Mod Podge around the pages of the book using a paintbrush. Apply one coat all the way around, let dry. Repeat.Applying Mod Podge to the edge of the book
  11. To finish, apply Mod Podge to the inside rim of the recess as shown. Go around the rim with the paintbrush and let dry. Repeat. You don't need to go on top of the pages.apply Mod Podge to the inside rim of the recess as shown

Nice. You can go to goodwill outlet and get a hardcover book for .50 Some very old! Then you don't have to feel bad about cutting up a new book

I have lots of my old Nancy Drew books. I still like them. I don't think I could give up one of them for a book safe, though it would be very fitting, wouldn't it? I keep forgetting to say I like the new blog design.
