I worked more than 80 minutes Monday morning on paper-piecing. I thought it would be good to start with a pattern that I've already had success with. My approximately 100 minutes (jumping up a couple of times to move clothes from washer to dryer, etc.), yielded two fan arcs. At the beginning, I had to rip out twice, but by the last three blades on each fan arc, I'd hit my stride and was doing well.
