Enjoy the process. I did! Recap: I had an old acrylic painting on a piece of 18 x 18 inch masonite. It was very textured because when I gessoed the masonite, I added a sheet of tissue paper and scrunched it around with my fingers to make a few ridges. To prepare the surface to accept pastel for a new painting, I spread Golden Acrylic Ground for Pastels over the old painting with a palette knife, intentionally making additional texture with my strokes. When it was dry, I used PanPastel for the first layer of color(s). After that, I applied pastel sticks as usual (the end, the side, poking, dragging). I love the way the ridges and high areas grab the color and valleys don't get any unless I go back into them with more pastel.
