Begin from the supplied pre-folded paper first frame. Locked oblique camera. Keep the two left-edge clamps and the held outer edge stationary. Move the free right outer edge a little toward the left so the existing accordion closes modestly. Keep one continuous blank strip with the same four stiff panels and the same three alternating internal creases. Panels change angle at those creases instead of stretching, flowing like fabric or growing new pleats. Preserve their original adjacency and front/back appearance. Finish as a shorter still-readable accordion, not a completely flattened stack, then hold. No tearing, extra fold, hand entering or camera move.
