It's a question worth asking. If you read the previous post I'm sure you're thinking about what you can do to prevent loosing of damaging your grimoire. But sometimes it can't be avoided, and if you do loose your precious book, it's a good idea to be able to receive some funds to make a new one. How do you do that? Again, with an ounce of prevention. Make a list of all the supplies you have bought for your grimoire, from paper and ink to binding glue and book leather. Think back to the beginning. If your grimoire was once housed by something different such as a three ring binder, include that into your costs. If you write by hand, include an estimated cost of the pens you have used, whether that includes three 20 count packs of ball point Bic pens or a Chaeyhane feather dip pen and four bottles of Aladine calligraphy ink. Have you bought a thumb drive or other portable gadget to store your digital grimoire? Count that in. If you do hand illustrate your book, include all art supplies used. Just really scour the nooks and crannies of your mind to include every penny you spent on your grimoire.
So what good will all of this do? Well, not only will this reinforce your appreciation of your grimoire, but even better, you can insure it so that if it is ever lost, stolen or destroyed, you can claim that money to cover the costs of replacement. And once you calculate how much money went into making your grimoire, you'll really appreciate that security. You will also know how much to insure your grimoire for if you must ship or mail it somewhere.

As a final tip, make sure to keep a copy of the costs in at least two places!
