  • Patent number: 4563154
    Abstract: A drawing stencil tablet to aid a child to color and draw includes a planar stencil plate having interior openings defining tracing edges that outline a character or shape. A plurality of spaced-apart locating posts project down from an edge of the plate and engage in registering openings in a stiff planar base when the plate is placed flush against an interior area of that base so that a base margin extends all around the plate. When the locating posts are received in the base, movement of the plate relative to the base is prevented so that a child can trace or draw on a sheet of paper sandwiched between the base and the plate with assurance that the position of the stencil plate on the paper will remain fixed.
