It's to paint directly on the canvas without any funny business, as it were, and I use almost pure turpentine to start with, adding oil as I go along until the medium becomes pure oil. I use as little oil as I can possibly help, and that's my method.
Edward HopperYes, linseed oil. I used to use poppy oil, but I have heard that poppy oil is given to cracking pigment too, so I use it no longer.
