Kit for simulated stained glass article, article produced from the kit, and substrate for the article

A kit for producing a simulated stained glass article, comprising:

• (a) a light-transmissive molded plastic substrate having
• (i) a flat base portion with opposed extended major surfaces and
• (ii) an array of interconnected caming ridges molded integrally with the base portion and projecting outwardly from one major surface thereof, the ridges having dark opaque outer ridge surfaces facing away from the base portion at a substantially common distance therefrom, and said one major surface and said ridges cooperatively defining a pattern of outwardly open spaces laterally shaped, enclosed and separated from each other by ridges of the array, each of said spaces having an area of said one major surface as a floor, the ridges having side walls beveled at an angle, relative to a line normal to said one major surface, sufficient to enable release of the substrate from a mold in which said substrate is formed while providing a ridge side wall slope steep enough to enable precise placement of the stickers in the spaces and to minimize the beveled appearance of the side walls and the transmission of light around edges of the stickers when the stickers are placed in the spaces;
• and
• (b) a set of light-transmissive colored plastic stickers for mounting in the spaces of said pattern, the stickers of said set corresponding in number to the spaces of said pattern and respectively corresponding in peripheral shape and dimensions to said spaces such that each of said stickers conformingly fits into a particular one of said spaces, each of said stickers having a light-transmissive self-sticking adhesive coating for affixing the sticker to the floor of the space into which it conformingly fits as aforesaid.
