Hello Ilia.I have asked every good artist I have met, "why do you paint". Of course I am asking why I paint, I have never heard a satisfactory answer. Not even from myself.
Your title, WHY FRESCO gave me a little hope of a fresh attempt at an answer. You talked about fresco, but there was nothing personal there.
Would you like to take a crack at it?
Why do you paint?
Why do you paint with plaster?
