For all of my hobbies and projects I keep notes in matching Journals. I started this habit when I was about 15 so I have been writing journals for over 20 years. I have kept most of them, these are my crafting journals from the past five years. I leave blank pages at the beginning or end to write an index when I am done. I often reuse the recipes over and over as the years go by. It takes me about a year and half to completely fill one.
