At the end of the day it’s entirely up to you. Some people make their lather in the top bowl of their Moss Scuttle, while others opt to either face lather or make their lather in a secondary bowl (see Sara’s Bowl) and then place their brush in the upper bowl of the scuttle between passes. As a rule of thumb, the large size of Moss Scuttle is ideal if you want to make your later in the scuttle, while the small version is great if you want to just rest your brush in the top to keep it nice and toasty between passes.
