I keep a journal of the projects I work on as I work on them. That way I know when I made what, who I made it for, the time it took to make it, the fabric I used, where I got the fabric, and all the rest. My quilts will have a running history with them so years from now someone will be able to know all about each quilt.
Good luck with the daily lottery you have going. I had thought about that when trying to decide where to go eat sometimes. Never about what project to work on. Good thought.
