There are many forms, shapes, patterns and techniques used for making objects from clay. The shape of spiral came to me without any conscious process. It just appeared in front of me. I have accepted it for now as my official pattern and all I create is made out of many spirals.
In art, the hand can never execute anything higher than the heart can imagine.Raplh Waldo Emerson
I usually adjust the size and width of the spiral to the size of the product I am making. So the largest and smallest bowl have different parameters of spirals. Each one is formed in righthanded direction and made out of love and passion.
