Writing on decks for study purposes?

[Zephyros]

Just sharing that since I got my Hermetic about six months ago, I've been congratulating myself on it more and more. I keep it ordered in a specific way, and don't shuffle it, and have written the astrological and Kabbalistic attributions on it, and will probably add more to it, such as decyphering specific symbols. The fact that it is white makes it a lot easier to do this. I also like that the back is relatively clean, as I look forward to covering it in text! I feel this is an excellent study resource, and refer to it often. I couldn't do this with any other, but I purchased this deck especially for this purpose.

I'm wondering if anyone else does this?
