Which is for what? I haven't gotten my supply's yet, but I have a mug, soap and a brush on the way. Also a strop and a razor from a different place. Do I put the soap in the mug to use, and then need a scuttle to finish making lather in and to keep it warm? Or if I don't care about warm, do I need a bowl to finish making lather? Or Do I put the soap in a bowl and use the ceramic mug as a scuttle? Is the scuttle really needed or is it optional? More questions to come. Thank you all very much. And I have read all I could find here about making lather, and these are the questions I have after reading.
