These were made by student friends learning to use a paint spinner to create lovely and colorful backgrounds on round and square paper tiles. The class lessons were to experiment with different papers and mediums. First they learned how to use the spinners using markers, pencils and inktense pencils. We didn't have enough time to Zentangle, however, they have a wonderful start with their colored tiles to fill them in with tangles at their leisure. It was a very busy class with a lot of different things happening all at once with each person. I love showing the results and benefits of using a variety of paper and mediums. The results are so different.
