The technique you are referring to is often called "collage." Collage is a visual art form in which various materials, such as paper, fabric, photographs, and other objects, are assembled and attached to a surface to create a new composition. It involves cutting or tearing these materials into desired shapes and sizes and then arranging and pasting them onto a surface, such as canvas, paper, or wood.
The process of creating a collage allows for the combination of different textures, colors, patterns, and images to produce a cohesive and visually interesting artwork. Artists can choose from a wide range of materials to incorporate into their collages, including newspapers, magazines, found objects, old photographs, handwritten notes, and any other items that can be adhered to a surface.
Collage offers great flexibility and creativity as it allows artists to experiment with various materials, layering techniques, and arrangements. It can be a two-dimensional artwork or incorporate three-dimensional elements, giving it a multidimensional quality. Collage can be created using traditional techniques, such as cutting and pasting with glue or adhesive, or it can be done digitally using image editing software.
Collage has been used by artists for many years and has gained popularity as a versatile and expressive medium. It provides artists with the freedom to explore different concepts, themes, and narratives by combining and juxtaposing disparate elements into a unified composition.
