Origami begins with a flat sheet and ends with a form. Textile origami begins with a flat piece of knitting and arrives at the same place, through folding, pleating, and manipulating fabric that was never meant to stay two-dimensional.
Knitwear designer Rastus Hsu works exactly this territory. Geometric folds, precise pleats, knitted fabric behaving like paper that has been convinced it has an opinion about structure.
The results sit somewhere between craft object and architectural model, the kind of thing that earns a place on a shelf not because it's decorative but because it's asking a question.
