I was going to make one when I saw that there are several such entries.
I read each entry and saw that no one had created one like the one I made many years ago.
You see this approach allows the book to be flipped through whilst still keeping the secret compartment out of sight.
Thus is a TRULY secret book.
Step 1: Select a Great Page Turner
(Do ask the owner of the book for permission and do not use a library book....or a kindle)
I thought that this one had a nice appropriate title too.
Step 2: Don't Start at the Beginning
This is a tedious task as you now need to repeat this for every page until you reach the depth that you want.
Step 3: An Overnight Success
Step 4: The Cutting Edge
Step 5: The Plot Deepens
Step 6: The End Is Hard
Step 7: A Magnetic Plot
This is why the cutting started later.
A row of small but powerful magnets are pasted between the first two pages of the hole.
Next on the page just before the hole another row of magnets is placed. You will have no problem aligning them since they will snap into place as they are attracted by the row below.
Paste down the page before that and you have a secret flap that can be pulled back to gain access to the storage cavity.
Step 8: Nothing to See Here
Step 9: The Secret Within
Step 10: Oodles of Storage
Step 11: Thumbs Up
Millions in money
Or medals of honour.
Step 12: Secreted Diamonds
Note to nefarious fellons; the items shown are not worth millions.
Step 13: A Plot Twist
Note: in the picture you can just see the hole top left...so a little more glue and there's no more clue.
Step 14: A Happy Ending
A book with a secret that is less likely to be discovered.
A great hiding place for valuables or 'personal' items.
Of course no member of the INSTRUCTABLES community would have anything illegal to hide.
