ABSTRACT:
An apparatus including a series of rectangular frames of various sizes to accommodate each of the letters of the alphabet. The framework includes three horizontal centering lines dividing the rectangular framework, with the centering lines equally spaced adjacent a rectangular center space defined by the framework. A single vertical line bisects the rectangular space and is directed through each upper and lower side of the rectangular framework. The apparatus further includes magnetic strips mounted adjacent each corner of the framework upon a bottom surface thereof to receive a stencil adherably thereon to align the stencil in use, and wherein each framework further includes hook and loop fastener members to secure adjacent frameworks in a side-by-side relationship. Fiber optic transmission lines are directed through the framework in a modification thereof in lieu of the centering lines to illuminate the centering lines and appropriately divide the center space during light conditions for use by individuals.
