Having trained as a graphic designer in her native Netherlands and in Germany, Niki now lives in West Yorkshire, and returned to working with clay at the end of the 1990's. She writes:  I am intrigued by opposites and contrast: in- and out-side, lightness and heaviness, empty and full, sharp and soft, round and square, rough and smooth, bold and shy. I like to stretch the medium of clay to its limits. My work is more like a collaboration of materials than a conscious attempt to produce a controlled or manipulated result. We show here just a few examples of her exquisite hand-made pots.
