Hey @deked ! You're only doing it wrong if it's not working for you. I'd say you are face lathering, after loading your brush from a tub. With a shave stick the soap goes directly from stick to face, followed by scrubbing up a lather.
With bowl lathering you would take your soaped up brush and swirl it in a bowl with extra water to make your choice of lather. It's easy with a bowl to get the lather exactly as thick or thin as you like it. Then paint it on to your face. Yeah, you don't get as much scrubbing that way, but you fine tune the amount of lather. I like thin, wet lather with a straight razor and thicker lathers with double and single edge razors.
