“Folding it back is a chore.” “It never returns to its shape.” “The sleeve went missing months ago.” Kasané began with a stack of complaints like these, gathered from people who carried on using their old bags anyway, quietly annoyed. We wanted that resignation gone.

Most people fold along the creases the fabric already has. A second clue came from the non-woven caps worn on the inspection floor — a strip of accordion folds that opens into a cap, then returns to a flat band when both ends are pulled. We wondered what that structure would do at bag scale. The idea of a body that collapses all at once started there.

Turning it into a product meant cloth prototypes on borrowed sewing machines, then rounds of adjustment across structure, capacity, tension and weight. The requirement was that somebody holding one for the first time could work it out unaided. The chore became something closer to a small pleasure. The structure has since moved well past bags.
