That's good advice.. ..all the more so since I may well be forced to leave it [the painting] at that, as so often happens when the model doesn't come back. That's always been my principal concern, to make sure of getting regular sittings. Whenever I start something, I'm always afraid the model will let me down.. .They come, they pose, then away they go, telling themselves that he can finish it off on his own. Well no, one can't finish anything on one's own, particularly since one only finishes on the day one starts, and that means starting often and having plenty of days available.
