My own handmade black and grey paper, machine stitched onto hand dyed cotton fabric. Then I soaked it and rubbed the paper to get a peeling effect. The low wet-strength of the handmade paper made this really easy. After drying I highlighted some of the edges with silver paint.
Not really my kind of thing, especially in the monochrome "night" colours, but I can see this would be effective for bark or peeling paint.
