Outi Martikainen (Finland, 1962) was trained as a textile artist and has frequently collaborated with architects to make upholstery fabrics, acoustic panels, patterned glass façades and other ‘applied images’ meant to be integrated into built environments. To her, textile is both an institutional affiliation and a licence for constant technical innovation. Her image-making practice presupposes both composition (like most other artists’ work) and calculation (made necessary by her use of braided ropes and computerised Jacquard looms).
