Before 2018 concludes you may want to consider some sort of diary. Might I suggest the beautiful 2019 Lunar & Seasonal Diary by Stacey Demarco?
This is a full color diary. It’s spiral bound so it lies flat, making it easier to record notes in the space provided. There are profiles of gods and goddesses, seasonal spell castings, and of course detailed information on the moon phases. After the year is over, it becomes a great reference book and comes with its own attached bookmark to use to mark where you are in the diary.
