So I finally bit the bullet and decided to depot my Book of Shadows. Come along with me on my journey.....
What will you need for this project? An
X-Acto Knife (FYI don't google that, disturbing images) and
Your Fingers:

Your giant
Book of Shadows of choice, here I have chosen #2:

A
Palette,
Magnetic Backing, and a
Pen:

I chose a Unii Palette which comes with a sticky magnetic sheet that can be cut and labeled easily.
Take out the drawer of shadows:

Flip over the drawer, look for a corner, and start peeling:

Peeling is also steps 3, 4, 5, and 6:

You will eventually get to the inner cardboard:

Also peel off the front layers that surround the metal pans:

See how the pans are just glued to a single piece of cardboard:

You want it to be a thin layer underneath:

Now use your X-Acto knife to free the pans. BE CAREFUL:

Now shed some tears over the many trees killed to make your Book of Shadows:

The remaining paper should peel off easily:

You could swab the pans with alcohol to remove the glue, but if you are like me, you will slap some magnets on the back already:

Label and put into your palette of choice. Leave out Midnight Cowboy Rides Again as punishment for being a glittery mess:

Yay!
