Now a canvas has a texture, it’s a woven fabric
and you can exploit that to your advantage. Some artists like to sand their primed canvases
to be glassy smooth. I do not. All these little teeth here, the weave of the canvas and the
different textures of the priming are all important to me to use and it really grabs
the paints off of your brush and when you scrape it off as we’ll see, it reveals other
texture. And you can exploit that to all sorts of advantages. You do want to paint on primed
canvas because oil will soak into unprimed canvas and will eat away at it over time.
A lot of paintings on paper, on cardboard on unprimed canvas that were so popular in
the mid 20th century are having conservation problems now. So priming is important. You
do get to retain some texture though and you can use it any number of ways. So texture
is good to use to your advantage in a primed canvas.
