Playing with acrylic paints, I got very interested in Dot Painting, long known as Pointillism. There is a long history of representational art, dating back to the first known artwork. It's fascinating and I've been practicing a little, trying to get my paint the 'right' textures and the dots the sizes I want.
Here are my first efforts. The largest is 3" x 2 3/8" and the smallest 1 5/8" x 1 1/2".
