It looks very like the technique used by Koos van den Akker on this skirt
You sew a piece of jersey down with lots and LOTS of parallel lines, then cut between them, through the top layer only. and leave the raw edges to curl. With a woven, I suppose they would fray
The long strips on the Koos skirt are narrow jersey strips, arranged in swirls, and stitched down along both edges. Time consuming, but not [fortunately for me] an exact science!
The end result is tactile, and changes with washing and wearing
