Doesn't really matter which way. I always say that most brushes have a stand build in - they have their bottom to stand on.
Just make sure that a brush is completely dried before you put it into a cabinet or any enclosed area.
The evaporation creates a vacuum that sucks the condensed water up with the grain of the fibers. However, on the individual hairs, yes, the water evaporates out. My bad. I should have been more specific.Water does not evaporate up. It evaporates out. No matter, it still makes no difference whether you hang your brush or stand it up.
Well said.The bottoms of all my brushes are flat. Therefore, that is how they stand.
