Whiplash Lines: The Stroke from Thick to Thin

An Art Nouveau whiplash curve. It starts from a thicker point, extends along an S-shaped or reverse S-shaped path, gradually tapering as it goes, finally ending in a fine point or curling into a small loop; no part of the entire line is of uniform width, nor is any part straight. It appears in wrought iron railings, stucco reliefs, or stained glass lead lines. Avoid: making the line uniform in thickness, making the curves into regular arcs and waves, making both ends of the line equally thick, using geometric spirals instead of freehand curls.

一道新藝術的鞭索曲線。它從一個較粗的起點出發,順著一個 S 形或反 S 形的路徑延伸,過程中逐漸變細,最後收成一個細尖或捲成一個小圈;整條線沒有一段是等寬的,也沒有任何一段是直的。它出現在鍛鐵的欄杆、灰泥的浮雕或彩繪玻璃的鉛線上。避免:讓線條的粗細均勻、把曲線做成規則的圓弧與波浪、讓線的兩端一樣粗、使用幾何的螺旋取代自由的捲曲。
