In this work is the realm of lichens. Lichens are everywhere around us but generally unseen by many people. Lichens adjust and react to the circumstances of its surrounding: humid or dry. The responsive property of the lichens to humidity led to the investigation of this species in combination with the flexible properties of knitted textiles. The knit enhances the lichens’ properties in its stretchable, textural, and color possibilities. While activating the textiles through moisture, there is a change in haptic- and visual expression. Working towards a material library, the transformable properties of the textiles are being explored. Lichen in combination with knit is investigated in four categories: transformation, shape, texture, and dye. The lichen and the knit adapt their role according to the category and demonstrate the potential of their various collaborations in each category. In several countries, lichens are protected due to the increase in air pollution. Through visualizing and emphasizing these precious and unseen species, the changeable textiles aim to activate the viewer in rethinking human’s relationship to nature.
