What happened is that I fell in love with clay and pottery.

It fascinated me. Especially because of the touch. That is why ILA, the touch of cre- ativity, as I named my activity. Here, where I live now, in Perovo, Kamnik, where my mother was born, there is a lot of clay. I did not know that before. But I do remember how excited I was as a child when I always heard the clicking sound under my feet after a heavy rain. Hundreds of years ago, there were the so-called "cegunce” in this area, where bricks were made and pottery was thriving not too far away. The Slove- nian potters from whom I gained knowledge had their own clay pits. While making pottery and for most of the products, I also persisted in using local clay, especially when creating with younger children when I used clay for therapeutic purposes. I felt it di erently. I did not dig it myself, but I do process it manually with all the respect that I do not discard anything. At some point, I realized in a very special way that clay is a soil that we take it out from its breasts so that we can make “gold from the mud”, as the famous architect Jože Plečnik said for the potters.
