As a newbie to pastels, I am learning from books and from doing. (I had my first lesson in a studio when I was about 6, but have used media other than pastel, such as watercolor.). Going through Marla Baggetta's "Pastel Step by Step", A Walter Foster Artist's Library Series book, the very first example, the very first step, is "toning a piece of sanded pastel paper with a diluted wash of acrylic paint," yellow ochre in particular. I have never used acrylic but how hard can it be?
Here's my question: what are the advantages and disadvantages of underpainting with acrylic, watercolor, pastel, using colored paper, or skipping underpainting completely?
I paint on watercolor paper, several layers of gesso with marble dust in the top layer so gesso for tooth. I've switched to oil pastels but I use the same surface for both dusties and oilies. I also use canvas panels, hardboard panels, birch plywood all gessoed and some texture added such as marble dust.
With hardboard panels (masonite) , I often just sand the slickness off the masonite and paint on a clear gesso. Clear gesso has a lot of tooth for either soft pastels or oil pastels.
Toning a surface with acrylic is too slick for my taste. If toning with acrylic or underpainting with acrylic, I'll use marble dust in the acrylic mixture or more often will put on a top layer of clear gesso.
