REEVES-Sketching By Numbers Kit. The Sketching By Numbers system is the ideal way for the inexperienced artist to learn pencil-drawing techniques without having to design the initial composition. Pencil drawing is the foundation of virtually all forms of two-dimensional art. It can be a quick sketch, a finished piece it its own right, or the first stage of a watercolor, acrylic, or oil painting. Each kit includes six pencils that are perfectly selected to get you started plus an easy to follow step-by-step guide which gives you many useful professional tips on how various effects are achieved and how to understand and master the use of tone. Complete package contents include one pre-printed drawing on board, six sketching pencils, one pencil sharpener, and one instructional guide. Available in a variety of designs (each sold separately). Conforms to ASTM D4236. Imported.
