Yes. I don't do it often though. I just had to get my mind around working in reverse.
Glad you got another bobbin case to mark and play around with. Otherwise when you go back to regular sewing you could have a real time balancing your tension. Also the tension screw can break from repeated use, or so I have been told.
The only downside was that I needed more bobbins as I didn't want to have to stop to wind more. the threads I used were much thicker that sewing thread.
Enjoy.
