Mixed media in card making refers to the use of different types of materials and techniques to create a unique and visually interesting card. This can include combining traditional card-making supplies like paper, stamps, and ink with other materials like fabric, metal, or even natural elements like twigs or dried flowers. The result can be a one-of-a-kind card that is both beautiful and tactile. Some popular mixed media techniques in card making include collage, embossing, and using stencils or masks to create dynamic backgrounds.
