Abstract
A drawing tool is provided for assisting artists in transcribing images onto a blank medium. The device is a drawing frame of geometrical shape and has a plurality of notches disposed along the outer perimeter length. These notches are channels cut out of the edge, forming protruding segments between any two notches. Protruding segments are used as anchor sites for a series of elastic threads. A portion of the threads is wound around protruding segments disposed on opposing dies of the frame body, thereby stretching the elastic thread across the front surface of the frame body. A first grouping of the threads is secured in parallel lateral alignment, while a second group is secured in a parallel longitudinal alignment. This configuration presents a grid pattern that can be laid over an image or blank piece of paper to serve as a guide for transcription.
