ABSTRACT:
A movable grid drawing frame consisting of two square flat frames connected at their corners so as to allow a narrow slot between their respective faces. A number of elastic grid strings inserted into the slot and positioned horizontally and vertically across the drawing frame opening defined by the four sides of the frame. The elastic strings are held in place by sliders attached to the respective ends of each of the elastic grid strings thus maintaining each elastic grid string under slight tension across the drawing frame opening. The sliders to which the elastic strings are attached allow for the free positioning of elastic grid strings across the frame opening in ways that produce a variety of grid patterns through which the user may view a subject. The elastic grip string patterns possible by the arrangement are unlimited because the elastic grid strings stretch and are movable allowing in manipulation of grid string patterns to meet the individual requirements of the user.
