Scrivener. Although I still make use of paper, I keep my entire outline in Scrivener. I didn’t for the story I wrote before my current one. I kept them on index cards. Then I got sick and didn’t write for a month. And misplaced my cards. Scariest week of my life, thinking I was going to have to recreate that outline.
Then and Now
Comparison of where I was in the writing process and where I am now. Sometimes, it’s the same place.
