Sheep class has been learning about ‘Op Art’ – art that is based on optical illusions. We began looking at the monochromatic work of Bridget Riley, and exploring how she used parallel lines and experimented with contouring to create a sense of movement in her work. We practised pencil drawing in our sketchbooks in the style of Bridget Riley, and we are now completing some collage work in which we will be incorporating more colour (as Bridget did in her later works).
