ya, I just use blank journal books from the dollar store.
I like the ones that have a page-marker,
and that have an elastic to keep it closed,
also I have graphite-lead piece for writing.
I write magic-spell book on the first page,
and then I keep it as a captain's log,
of where I'm going, what I'm casting,
and where I am, what significant events occurred.
It's always great to also write out the results of the spell.
I typically write the date at the top,
and then whatever it is I like on the page,
sometimes I make drawings,
write down dreams.
I keep it in my pouch,
it's an ideal fit.
