Circles–Third Layer

I did some sun painting today with Setacolor paints.
Of the 5 or 6 pieces I did this was the best one.

This piece was started quite a few years ago. Before I started it today it had two layers of pattern made with thickened dye. Each layer had a circle theme so I wanted to continue that.
I found some circular plastic pieces to use and they were the perfect thing to add layer number 3. I now consider it finished.
