To gain a higher degree of control and reduce undesirable edge rippling, mirrored arcs were cut out on both sides of the desired fold line. While removing material in following this method made folding easier, the resulting fold was predominantly informed by the arc length, placement, and curvature. In every case, the resulting fold differed greatly from the desired (more linear) folds. The resulting overall form exhibited the most torque/twist.

Arcs were then tested independent of the main guiding folds from previous tests to more clearly establish the relationship between the arc shape, distance from anchor point, and resulting fold. The arc cut strongly directed the fold, requiring little pressure to perform and only allowing that specific fold to be made. Allowing the arc to guide the fold resulted in clean edges and minimal warp and ripple. 
To reintroduce a degree of unpredictability and warping from previous studies, focused perforations were combined with the arc cuts.
