The Monster Book of Monsters

Intro: The Monster Book of Monsters

This DIY was a long and bumpy ride. After losing video footage and having to start over, running out of clay and then buying the wrong kind, missing audio files (for the video tutorial), and getting sick for a week right in the middle of making this prop - it's finally done! I'm very happy to share with you the Monster Book of Monsters!


You'll also need to download my free templates available below. I am not referring to the instructables PDF (which requires a paid subscription). You want to download the .zip file.


Step 1: Video Tutorial (3 Parts)

Step 2: The Teeth and Tongue

Use the polymer clay to shape the gums/teeth and tongue. I looked at several screenshots of the monster book as reference. Check out the photos and video tutorial (part 1) for more details and tips.

Bake the clay in the oven according to the instructions for the clay you're using.

Once the pieces cooled down and fully hardened, use the acrylic paints to color them. I used an off-white color for the teeth and pink and crimson for the gums and tongue. Use screenshots of the monster book as reference as you paint.

After they dry you can optionally coat the gums/teeth in matte finish and the tongue in gloss finish.

Step 3: The Tentacles

Shape your tentacles out of foil in varying sizes from small to large (based on screenshots of the real book). You then want to roll out some clay in a thin layer and cover each tentacle so you can't see the foil anymore. To make the suction cups, start off by rolling small balls of clay, sticking them where the suction cups would be, and then use the back end of one of your paint brushes to poke a hole in the middle of each clay ball to make it look like a suction cup.

Again, bake the pieces in the oven according to the instructions for the clay you are using.

Once they are hardened and cooled down, paint the bottom of the tentacles an off-white and then paint the top of them a light brown.

After they dry you can optionally coat them in matte finish.

Step 4: Preparing the Book

Now that we have the time consuming part out of the way, we need to get the book ready to be transformed into the Monster Book. I used an old dictionary because it was the right size.

Use an X-Acto knife to carefully separate the cover (front, back, and spine in one piece) from the inner pages.

Now trace the size of the inner pages (all together) onto a large piece of cardboard. We are going to make a rectangular box that should be the same dimensions as the inner pages. I traced the length, width, and thickness of the inner pages to make my box template. Also, make sure to sketch some flaps around the template so you can fold them in and glue the box together (reference the images and video for more details).

Now just use a hot glue gun to glue the box together.

Step 5: The Inside Pages

Print out the inner pages on regular paper. You should have a blank page, a cover page, and one interior page. The interior page and the blank page can be single sided, but you want the cover page to be double sided.

Next print the side texture single sided on regular paper.

Now cut out pieces of the side texture to cover the sides of your cardboard box which will be visible once we attach it to the book cover. Use a glue stick to glue them on. This will make it look like the sides of a closed book.

You also want to glue the single interior page to the top of your box. This page will be visible when we open the book.

Set the other two pages aside for now.

Step 6: The Eye Slots

Print the cover template on regular paper, cut it out, and use a glue stick to glue it to the front cover of your book. This is just a template to help us visualize where everything is. I've sketched where the eye's should go between the top and bottom lines of the book title. Use your hot glue gun to shape the parts which our eyes will attach to. These four "humps" should be a little less than an inch high and taper off as they stretch toward the spine of the book.

You'll want to do one layer, let it dry, do another layer, let it dry, etc...

Now take your four eyes and line them up where they should attach to the humps. Cut out slots in the glue humps for the screw like parts on the back of the eyes to slide into.

We aren't going to attach the eyes just yet, so set them aside for now.

Step 7: Attaching the Teeth, Tongue, and Tentacles

For the tongue, cut a slot in the side of the cardboard box you made and simply slide the tong into it. If you need to secure it on, just use hot glue on the inside.

For the teeth and tentacles, hot-glue them onto the cover of the book using screenshots as reference.

Step 8: Binding the Cover in Fur

Cut out a piece of fur that will cover your... cover. This should also extend out around the book by about an inch or so. Start at the front cover on the right side and hot-glue a section of the fur down. Now measure out where the eyes will go and poke holes in the fur fabric in those locations. push the eyes through and secure them on with the little plastic washers that came with them. The screw like parts should now be able to sit in the slots we cut for them on the hot glue mounds. As we glue the fur onto the cover, glue the eyes onto the mounds as well.

Continue to glue the fur down until it covers all of the book cover (front, spine, and back).

Now you can trim the fur around the edges and hot glue down any spots that are loose.

Step 9: Putting It Together

Hot glue the box we made for the inner pages onto the book cover. Start at the spine, then glue down the back cover. We should now be able to open and close the front cover of the book and see the inside page.

At this point we can all the cover page and blank page to the interior of the book. With a glue stick, glue the very left edge of the cover page as close to the spine as you can. Now you should be able to turn the page and see the inside page below it. The blank page can be glued to the inside front cover.

Step 10: Adding the Title and Details to the Cover

Print the cover template again, but this time on heavy card stock. You could use it as is, but I decided to go over the title letters with gold leaf to make them look shiny and gold. I just used a DecoFoil adhesive pen to trace the letters and then covered them with gold leaf. Use a soft dry brush to wipe away all the excess gold leaf. This is super messy (the little extra gold pieces get everywhere) but totally worth it.

With scissors, cut out "The Monster Book of" and "Monsters. Use hot glue to attach the title to the front of the book, according to reference images. You will probably need to significantly trim the fur in the spots you're going to glue the title to.

Step 11: Attaching the Strap and Buckle

Next, just cut an old belt down to size and pop a hole in it so you can fasten it around the middle of your book.

Easiest step ever.

Step 12: You're Finished!

That's it! You're all done!

Awesome piece, looks just like the original! The only thing missing is a motion detector and some kind of excenter motor to make it shake or move... But I guess that would be a little too creepy. Thanks for sharing!

This is pretty awesome. I may have to try making one for my sister who is a HP fan.

You absolutely rock, what a very cool book, I made one years ago out of a notebook and sold it at a craft sale to a grade school teacher and now I want to make one for myself. Thank you so much. Yours is so much better. Susan

Cool! That would be perfect with an Arduino board and few motors to make it move!

Yes, there are a lot of space for a controller, motors etc inside the book.
