Mills' practice is influenced by what she refers to as concepts of ‘transitional space’. Such spaces act as interfaces between outside and inside, stillness and movement, raw and processed. The artist has drawn parallels to ceramics in her basketry practice, particularly in her formation of open-ended forms and vessels. Notably, both traditions have worked towards forms that simultaneously inhabit and contain space. Mills works primarily with traditional basketry techniques that centre around intricately combining plant-based materials. In her work, basketry is highlighted as tradition and as philosophical mode to explore process and focus. Her forms are densely layered with alternating materials, each intensively woven and combined. Returning to the theme of ‘transitional spaces’, her baskets serve as delicate connectors between maker and viewer.
