ABSTRACT:
An optic art kit is disclosed comprising one or more pieces of a pre-cut frame material (a section of which is constructed with an internal light source), a sheet of abradable material, a one scriber having engraving and abrasive portions, several triangular supports for freestanding assembly, and line drawings or other pictorial material for use as a pattern when abrading the sheet material. The pre-cut frame material is extruded from plastic and has a flat base, substantially perpendicular side portions and rounded top portions which terminate in parallel spaced apart clamping flanges which engage opposing sides of the sheet material. This frame material is preferably mitered so that it may adhere to all the edges of the sheet material to frame the sheet or, alternatively, to cooperate with one or more triangular supports to create a freestanding assembly. The resulting kit produces a professional, attractive edge-lit product which may be used for decoration or to provide information.
