I am interested in hearing what others are using for their painting surfaces.
I have been using canvas that is primed with gesso and that I put down two layers of Hilbein silver white (lead white) foundation that is tinted medium value using umber.
The sizes I have used are 11x14" and 16 x 20". I think the 16x20 stretchers could probably use some middle bars for better durability. The 11x14" are probably small enough to not require that.
I saw that some artists will put canvas around cardboard or something like that and then later resize it (crop it) and stretch that onto stretcher bars. And some artists will take their finished pieces off the bars and even store their paintings (canvas) off bars. and restrech them later.
For small paintings some just paint on board instead of using canvas. (anything over 11x14 maybe.
What have you been using and how do you feel about quality and durability?
