Brush Holder for Painters

The purpose is to help separate brushes with pigments while drawing oil paintings. I first had this idea in an oil painting class where I had to hold all the brushes in my left hand for long periods of time until my fingers cramped. I designed this pot of decent height with holes on the side to hold brushes easily for me while painting. My classmates greatly appreciated my creation and asked for commissions. Such type of vase is not entirely my original creation, but this idea of using it as a brush holder is worth generalizing.
