Q1 - I want to paint a large wood panel (7'-6" x 4'-0") .
Would you attach the canvas over the panel, gesso and paint?
Would you give the wood panel (no canvas) an acrylic coating with gesso on top and paint?
Q2 - I have seen artists hang large loose canvas on a wall. Finish a painting and then stretch the painted canvas over a frame when completed. Would this not cause the paint on the canvas to crack??
