Drawings and sketches

With some of his paintings, Repin made one hundred or more preliminary sketches. He began his works with sketches in pencil or charcoal, using lines and cross-hatching. Often he would rub the drawing with his finger or an eraser to get the precise shading that he desired. He sometimes used drawings or paintings of his children to experiment with different points of view. For his large paintings, he made very detailed studies, experimenting with the composition and judging the overall impression.
