The work explores the fold as a movable spatial structure and investigates the design scope of knitted surfaces when combined with pleating. The starting point is knitted textiles that are permanently transformed into three-dimensional structures through the technique of pleating. The textile collection entFalten (unFolding) provides an insight into the experimental dialogue with material, form and colour. In this, colour is deliberately applied in such a way that it adopts the form of the folds in order to reinforce the three-dimensional effect of the textiles.
