Throughout her practice Hannah employ's worthless materials, decoration, absence and temporality to question preciousness. Materials such as dust, ash, dirty water and grime are resurrected from detritus into decoration. Some installations however use even less than this, they employ absence, processes of taking material away, working with nothing. The removal of materials through washing, scrubbing, erasing, pricking, cutting and sweeping are actions that allow absence/non-material to be equally as important as the presence of materials.

Installations such as The Wonder of Rare Experience  are created by hammering pins and nails into the wall to make small holes which create a complex ornate patterns. The visual nature of the work is extremely subtle. Standing in the middle of the room you cannot see the work. The viewer must move towards, away and pass closely alongside the wall in order for the pattern to be revealed, in this way the work also the work is experienced durationally.
