A journal is a lot like a human - it ain't what's on the outside...
A. Crowley said that we should have our own magickal diary (journal). 777 was his version. IF we follow his directions, our journals will be different. Like my Tarot Journal and your Tarot Journal will be different.
I like sprial back notebooks. I fill one with notes, I move onto a new one. Now, years later I can go back and read my early journals and compare, see my own growth...measure the change in my own stature!
A journal should be battered and worn from being carried around - there you are in a coffee shop and a woman walks by in a hat, for some strange reason you think of the Queen of Pentacles, so you write about her. If you don't have your notebook, you won't write. Your journal should go with you wherever you go - as should your deck.
A human, ages, wrinkles, sags, shows the scars of a thousand insults in our gait - as our journal should on the outside - the true beauty lies on the inside - with our contents!
Of course this is simply my opinion...
