Petrykivka is a style of painting which originated from the small Ukrainian Petrykivka village. This style of painting utilizes thousands of small brushstrokes, blending together to present a seemingly seamless element within the painting. The brush used for these paintings are in themselves unique, being hand-made from cat hair. Olena Skytsiuk, a renowned Ukrainian painter is one of the few artists who are preserving this dying art. She has been a member of the National Artists Union of Ukraine since 1978. Her work can be found in museums and private collections all over the world.
