Thanks so much to everyone who replied. First, it’s good to know I am not the only one who has struggled with this. Second, I got some good ideas.
For now I am trying this: whatever I am working on when I “close up” for the day, will be the same thing I work on when I start the next day - either quilting or piecing. That way everything is good to go in the morning. I can break for lunch or whatever and come back refreshed to “make ready” for a different process. Sounds good. Now, to see how well it works.
