The Art of Frottage: A Forgotten Technique by Matisse - Apparently.
In the 1910s, renowned artist Henri Matisse used a technique called frottage to create intricate drawings. Frottage involves applying paper to a surface and rubbing it to transfer textures and patterns. Matisse used this method to create a series of drawings, known as "paper cut-outs," which were exhibited in Paris in 1947. This technique, though unusual, has been verified through Matisse's own notes and the preserved artworks, making it a fascinating example of the artist's creative process.
