Andrea Grau also experiments extensively with paper, approaching it as a material with its own expressive potential. Her work encompasses various techniques such as printing, drawing, engraving, and cyanotype, allowing her to explore the interplay between image, texture, and process.
She often combines multiple methods of reproduction within a single piece, creating works that evolve through repetition and transformation. She is interested in process-based creation and the material traces that each gesture leaves behind.
