Timing myself with this project to discover how much time it takes to spin up roving. I will make two ply, and will not set it. Yards per hour? Ounces per hour? I just don't know yet. I am using a kitchen timer which rings on the hour, so I can get lost in my zone and enjoy the fiber moving through my hands. The colors are lovely, both the natural and the hand dyed (Madder, Golden Rod). It's a lovely learning experience.
