How do curved structures fold? How could one design origami with paper that is not intrinsically flat? Inspired by the natural folding of pollen grains, a biological process of high importance, we investigate how simple geometrical and mechanical design principles determine the folding pathways of structures with non-zero intrinsic curvature.
