McDonald explores the theme of fragility in natural habitats through large-scale collages made of tissue and rice papers. Surfaces of the collages are actively tactile evoking layers of time and memory, and the delicate materials carry their own messages of transience and fluctuation. The translucent papers have been tinted with acrylic paint, then torn, crinkled, folded, woven and reassembled to create large, floating constructions that represent the fragility of threatened natural habitats. Their tactility is further enhanced with drawing, text and water-colour.
