"Lining" involves first mixing a "lining compound" from spackling powder, a hardening agent, and pigment. They then squeeze this through a nozzle so as to create raised, floating lines that have all the beauty of relief carving.
所謂「梭線」，就是將一般粉刷牆壁用的補土（俗稱批土），加入硬化劑及色料調製成的「粉線土」後，裝入擠壓器內，以粉線在帽筒及配件上勾繪線條，藉由粉線的浮凸立體感表現浮雕之美。
