Every Brush Knott be it Boar, Badger, Synthetic, Horse, or some Mix of the Bristles mentioned to the left have their own personality.
When you decide to make a Lather with any Brush there is a learning curve depending upon the Soap, Crap, or Cream being use. I will call this stuff MATERIAL.
It’s like a science experiment, until you figure out the Material to Water Ration, and is your Brush a Lather Eater, or Lather Friendly.
When you finally get this math problem figured out, m eking a GREAT LATHER is as easy as One, Two, Three.
