ABSTRACT:
A drawing kit is provided comprising a drawing pad, a plurality of transparent geometric shaped templates, and a double pencil holder. The pages of the pad have intersecting perpendicular lines and the templates have orthogonally intersecting indicia so that the templates may successively be selected and their indicia intersections aligned with line intersections on the drawing pad, and the outline of the template traced onto the pad so as to create more line intersections on the pad, and the successive process repeated to generate composite geometric designs on the pad. The double pencil holder has a pair of substantially parallel bores therethrough which allow pencils to be force-fitted therein securely enough to resist dislodgement from normal drawing forces. When the holder is kept at a constant angle with both pencil points on the paper, an image or portion thereof drawn with one of the pencils will be duplicated by the second pencil in a position slightly offset from the first image, the second image being useable to give an effect of depth to the first image. The double pencil holder is used to trace portions of the templates in the above procedure so that composite complex geometric designs having three-dimensional appearances may be created.
