Curved Folds and Wave Forms
曲线折叠与波浪形生成

曲线折叠能生成叶片与波浪。先在板上用模板画出连续的 S 形或弧线折线，沿每条弧线手工折出；在折叠态交替锤压相邻折谷与折脊，展开后相邻单元相互推挤形成连续起伏。控制折线的疏密与弧度，可调节波浪的"频率"与"振幅"，是做植物形态的关键技法。
Curved folds make leaves and waves. Draw continuous S or arc fold lines with a template, hand-fold each arc, then alternately hammer adjacent valleys and ridges while folded; on opening, neighbouring units push into a continuous undulation. Varying line spacing and arc radius tunes the wave "frequency" and "amplitude"—the key technique for botanical forms. ---
