"I have been working with silicone for years. While I was still studying, I painted on unusual materials, for example on a soft felt. I like material that easily surrenders – you can tame them and “go out” to the third dimension, and at the same time sanctify something that is considered ordinary. Once, I painted on sponges over twenty centimeters long, which create a great illusion of sandstone."
