I started out face lathering. That's all I did for about a year. I just didn't see the purpose of bowl latherng. This last spring I tried it and found that it was helpful in troubleshooting a lathering problem. I also found that I could get warm lather by floating the bowl in a sink of hot water, so continued to bowl lather as kind of a poor man's scuttle. I went back to face lathering over the summer.
I've only just begun, but I have a hell of a time building a lather on my face. I'm fine in the bowl and I too let it sit in the sink full of hot water. I the warm lather is simply perfect for these cold fall mornings.
