Playing with brushes exercise:  This holiday season I treated myself to a purchase of Creature Art Teacher, Aaron Blaise's texture brushes.  They were on sale.  Amazing brushes.  They mimic brush on canvas.  They are also pressure sensitive and he sets up a ready to go file with a canvas texture on the bottom layer (PS), a toned layer, a drawing layer and a canvas layer on the top that is multiplied.  I bought the canvas texture brushes as well as the watercolor brushes.  Have not gotten to these yet.  The link is:  https://creatureartteacher.com/product-category/tutorials-lessons/brush-texture-sets/
