I have what I call a formulary. It's kinda like a grimoire, only there's no spells or rituals, just basic instructions for concoctions, herbs and their uses and so forth with things like stones and what not. It's like a witchy cookbook of sorts.
yeah ive got summit like that, but i think i might add like a leaf of a herb im writing about, because this book will be given to my children when im gone. ive also got a scrying book where after ive woken up ill write a quick note about what ive seen, so i know what to look out for the next few days, and ive got a dream diary which ive given up on because i forget to write in it
