I work on one project at a time and I always break it down into sections and work accordingly. I am still learning my new long arm, so I prefer to have at least 2 tops done so I can work back to back on those. This allows me to gain more confidence and experience rather than waiting a month or more between each top and forgetting everything I learned 🤪.
I am however debating working on a fast and easy quilt along with a more involved one just to use more of my stash.
