yup, i do use a small (a5) file as a 'Faerie File' part of which is an 'oracle journal'. It is good because I can insert or extract pages as needed. I am a naturally messy person who makes a big effort to be organized, so i have carefully organized the file with coloured seperators and everything! (don't laugh, my first attempt descended into an utter chaos).
My sections are:
1) a first page with a dedication to my Guide and thanking all the Fae
2) Exercises from the book (Grouping the Cards, Power Cards etc)
3)Notes on each card 0-65 (keywords, symbols, colours etc)
4)Readings (I jot down the date, spread, cards, interpretation)
5)My connection to faery (meditation, dreams, odd events etc)
The rest of the file has stuff on Faery folklore, recipes, herbs, crystals, runes of elfland, quotes, favourite poems, book lists etc
I imagine it would seem a tad anal to some, but I am VERY scruffy/dizzy and tend to fill up notebooks randomly then lose them. this way i have a nicely laid out 'history' of my connection with the cards to refer to.
