There are many ways to paint a painting.
I have never learned to paint a painting so when I, many years ago, first painted a painting I had to try my hand at it. As with everything I do, I learn it by trying.
I figured out a cut a kitchen sponge into small pieces and dabbed a painting up with acrylic paint because that was the only way I could figure out how to make shadows. That way I could dab paint “wet in wet”. New colors on top of the already wet layers of colors I had just painted. That way I could keep dabbing colors on and mixing the colors until I had the shade color I wanted. So simple and easy.
To this day, it’s still the only way I can paint but what does it do. Just the result will be as you want; 0)
Kitchen sponges cut into small pieces and act as paint brushes. Simple and efficient.
