Got to looking at Cella in the forum this morning, and have a question on using it (or any other "soft" soap). Given that one gets it in the red bowl, how do you take it out and lather it? Swirl the brush in the red tub? Scoop some into a bowl and bowl lather? Put some on the tip of the brush and face lather? Rub it on your face and face lather? Curious. Thanks!
