This is a pandan leaf that has been made in such a way. The leaves are woven, forming knitwear overlapping each other to form a mat for sitting, relaxing, or lying down.
In our area, making mats from pandan leaves has been done for a long time. This is a work of human hands, which requires patience and thoroughness of the knitters.
I shot this woven pandanus mat up close using the assembled macro lens, which I attached to my smartphone.
