This could be a great magic trick instructable but I decided to stick with its real purpose of putting book cover artwork on display.
I have tons and tons of case-bound books with very artistic covers which are packed away in boxes, hidden away in bookcases or that are on shelves or covered up by other books or magazines.
Finding clear space on a shelf or table to stand a book up so that both sides can be seen is a challenge but not so much of a challenge when walls and doors are recruited to make viewing covers possible instead.
Here then is an instructable of how to display the artistic covers of a book when space on a table or shelf is not available for displaying, by using a door or wall to display book covers instead.
Step 1: First, Get Yourself a Case-bound Book With Some Artistic Covers
If you paid as much money for textbooks as I did, which are now very much out of date, you may at least have the consolation of the artwork provided by the publisher on the covers
If you are in need of books to use for this project then ask your school or local librarian if she (or he) can provide you with any that have been withdrawn from circulation. Once a book in a library looses favor among readers you can usually get the artwork for free.
Step 2: Get Familiar With the Parts of a Case-bound Book
Locate the passageway between the case and the liner. Find the signatures and the signature boundaries. Paperback books can be used but do not have a passageway or signatures. Instead the pages are glued directly to the back.
Step 3: Take Measurements
1. Width of the book (how much room it takes up on a shelf), excluding the covers, from first page to last page. (for page binding)
2. Page height. (for hanger rod)
3. Page depth. (for hanger rod and loop)
4. Book weight (for sizing hook and line)
Step 4: Make the Hanger Backing
Cut a piece of aluminum sheet about three quarters of the width of the book and 1" longer than the page height. Put a small indentation on each end, about half way from each side.
Step 5: Bend the Ends and Insert the Strip
Bend the ends of the aluminum strip to a 90 deg. angle, 1/2" from each end and carefully insert the strip into the passageway between the back and liner. You may have to slightly unbend the strip but at least get the bend started before inserting it into the spine.
Step 6: Find the Last Page
Open the back cover of the book and thumb through the last few pages until you find the last numbered page.
Divide this page number by 2.
If, for instance, the last numbered page is 3052, divide by 2.
Let's see... I got 1521.
Open the book to the page number you calculate. In this example the calculated page number is 1521.
Determine whether the two adjacent pages have the same signature.
If not, reopen the book to a page that is a little higher or lower.
The middle of either the left or right signature would be good if it is not too far off center.
Step 7: Bind the Pages
I used Berkley Big Game monofilliment fishing line but you can use most any monofilliment fishing line - even generic line from an old fishing rod.
Cut a couple of lengths long enough to go around the book head to tail, back cover to front cover, plus a little extra for tying a slip knot.
Open the book to the middle pages found in the last step.
Lay half the length of the monofilliment across the page a couple of inches or so from the edge of the page running head to tail and close the pages over it.
With the cover of the book still open lay the other half of the monofilliment between the open cover and the page the cover will touch when closed.
Place the unknotted end of the line through the slip knot and pull the line tight. Be sure that the pages stay flat. This can be done by closing the cover and putting a little pressure on the book while the slip knot is tightened. When tightened the slip knot should seize the line and keep it from slipping.
Open the cover and tie a Fisherman's knot on top of the tightened slip knot to keep it from coming undone.
Do the other half of the book in the same way.
This step will make mounting the book a whole lot easier, especially if you mount a big heavy book.
Step 8: Make the Hanger Rod
Cut a length of aluminum fence wire twice the page height. (Most any other type of wire will do but aluminum wire is easier to work with.)
At each end make a small loop around a pencil and then twist the short end around and around below the loop to end up with a sort of Hangman's looking noose. 5 to 10 turns should be enough depending on the weight of your book. Cut the excess off and use pliers to press the cut end closer to the wire.
Open the book and Insert the hanger rod between the back and the aluminum backing. Stop when 1/3 of the extended hanger rod is sticking out the head and 2/3 sticking out the tail.
Fold the rod over and into the indentation you made previously in the aluminum backing, toward the center of the book so that the hanger rod is caught in the indentation.
Step 9: Make the Hanger Loop
Now use two to five strands of monofilliment line (or package twine) to make the hanger.
Make a loop with the line or twine to go through both loops of the hanger rod.
Tie the hanger loop securely so that when one side of the loop is pulled tight it will not extend past the margin of the page with the book closed.
You may have to adjust the length of the hanger loop in the next step. Sometime a slip knot can make the adjustment a little faster.
Step 10: Mount a Hook on a Wall or Door
The size and type hook depend on the characteristics of the book. For a heavy and large book a bigger hook is needed.
In this example a smaller hook is used but a hole is drilled in the drywall right up to the stud to get the point of support closer to the drywall and to be sure all of the threads on the screw can go into the stud.
Small hooks will usually work since a large portion of the weight of the book will be carried by the friction of the surface of the wall.
If you plan to do more than one book a neat trick is to mount a 1" strip of hardwood wood inlaid across the studs level with the drywall or mount a wider piece on top of the drywall as a backing for the hooks. This really looks super cool, but I need more time to do more than one or two books.
Step 11: Mount the Book
Have some twine or a set of small bungee cords ready to hold the book closed. You will need to do this unless your have a helper until the monofilliment is tied.
Readjust the hanger rod ends to create a 1/20 head and 19/20 tail extension as shown in the photo and hang the hanger loop on the hook.
Begin sliding the book up the wall while closing the book. Take up any slack in the hanger rod and loop as you persuade the hanger rod to slide back to its original 1/3 head and 2/3 tail division. This can be very, very tricky and can take a lot of patients and time, which may require you to consider using monofilliment line for the entire hanger. For heavy books you can double or triple the strands of monofilliment to make up for removing the strength of the wire.
Allow the book covers, hanger rod and loop to slowly take up the weight of the book as the book is being closed.
Once the book is closed raise and lower the book slightly to "seat" it more securely on the hook and take up any final slack from hanger relocation.
If you can't close the book then start over using a longer hanger loop. Your goal here is for the hanger rod and loop to be long and loose enough when readjusted for the book to close but short and tight enough for the hook to be hidden.
When the book can be closed and the hook hidden use twine or small bungee cord to temporarily hold the book closed.
Step 12: Secure the Covers
Now replace the bungee cords or twine, used to temporarily hold the covers closed, with clear monofilliment fish line.
I've had several books held to a wall and to a door for the past 8 months using this mounting technique. With all the abuse an occupied bedroom door can give, all that has ever been needed is a slight tilt adjustment.
You can use smaller hooks and monofilliment fish line to replace the aluminum wire hanger rod for lighter books and paperbacks.
