For the past several years, I have been painting on
gesso'd boards. I make them myself from a recipe
I'd learned from gilding.
They are very absorbent, and would allow me to work
in the "fat over lean method of painting.
But there's been talk from folks about oil primed surfaces.
They say it makes a difference, and to try it out.
I've had this underpainting white for many years. I stopped
using it because it set so fast. Also with the bottle of
artist medium, it set quick also.
I went ahead and mixed the underpainting white with the medium. It mixed like taffy,
but soon had it buttery enough to trawl on with a palette knife.
I will try this oil primed surface out and let you know how it works!
