1968年，LeWitt开始制作直接在墙上绘制艺术作品的指南和图表。起初，他们使用石墨铅笔，然后使用蜡笔，彩色铅笔，以及后来的印度墨水，丙烯酸涂料和其他材料。 LeWitt的许多墙图都是由其他人使用他的指导方针执行的。 LeWitt表示，墙上的图纸永远不会相同，因为每个人都不同地理解说明并且画出独特的线条。即使在他去世后，LeWitt的墙图仍在制作中。许多是为展览而创建的，一旦展览结束就会被摧毁。 LeWitt墙绘图说明的一个典型例子如下：“绘制两条线交叉的所有组合，随机放置，使用角和边的弧线，直线，不直线和虚线。”这个例子来自马萨诸塞州剑桥麻省理工学院的“Wall Drawing＃122”。在20世纪70年代后期搬到意大利斯波莱托后，LeWitt开始用蜡笔和其他颜色鲜艳的材料制作墙面图纸。他将这一变化归功于他对意大利壁画的曝光。 2005年，LeWitt开始开发一系列潦草的墙纸。与他的其他作品一样，创作说明也非常具体。涂鸦以六种不同的密度完成，最终意味着三维工作。
In 1968, LeWitt began producing guides and diagrams for drawing art directly on the wall. At first, they used graphite pencils, then used crayons, colored pencils, and later Indian inks, acrylic paints and other materials. Many of LeWitt’s wall drawings are performed by others using his guidelines. LeWitt said that the drawings on the wall will never be the same, because everyone understands the description differently and draws unique lines. Even after his death, LeWitt’s wall map is still in production. Many were created for the exhibition and will be destroyed once the exhibition is over. A typical example of a LeWitt wall drawing description is as follows: “Draw all combinations of two line intersections, randomly placed, use corner and edge arcs, straight lines, no lines and dashes.” This example comes from the Massachusetts Institute of Technology in Cambridge, Massachusetts. “Wall Drawing #122”. After moving to Spoleto, Italy in the late 1970s, LeWitt began making wall drawings with crayons and other brightly colored materials. He attributed this change to his exposure to Italian murals. In 2005, LeWitt began developing a series of scribbled wallpapers. Like his other works, the creative description is very specific. Graffiti is done in six different densities, which ultimately means three-dimensional work.
