This video shows a sort of hyperbolic granny stitch cardi that’s done completely in 1 piece, no seaming at all. The join is more granny stitches to build up the front placket & optional collar or hood. It’s so mesmerizing to watch & I’m fascinated by the geometry.
Not sure I’d actually wear such a thing but I am sure I really want to try making it. Maybe in one colour or a variegated yarn like mandala.
